The density of the toner layer that is ultimately applied to the image roll 22 is controlled by varying the magnitude of the bias between the rotating electrode 211 and the counter electrode 212.

For example, toner applicator 21-1 can apply a blue toner, toner applicator 21-2 can apply a red toner, and toner applicator 21-3 can apply a yellow toner. The toners of different colors are preferably charged to the same polarity to enable electrostatic transfer of toner layers. In one aspect of the invention, the charge pattern generator generates the electrostatic charge pattern on a support before at least one toner layer is applied to the support. Get it from Dame: a starter kit with the reusable applicator and six tampons for $30.83 and subscription of 34 tampons for $10.49 (and choose how frequently you'd like refills delivered). In contrast to LID systems, the toners in a CEP system need not be pre-mixed to form a custom color because in CEP systems toner layers can be combined to form the custom color toner layer. In operation, the bias applied between the rotating electrode 211 and the counter electrode 212 is controlled, e.g. A contact electrostatic printing device, comprising: depositing means for forming a plurality of toner layers on a support, each toner layer initially having a solid concentration of 10-50% and at least two toner layers at least partially overlapping; and. The developed image is subsequently transferred, either directly or indirectly, from the imaging member to a copy substrate, such as paper or the like, to produce a "hard copy" output document. By reversing the bias, the toner will not be attracted to the rotating electrode 211. 1 (optionally excluding the transfixing device 26). 1 is a schematic diagram of a CEP apparatus in accordance with the invention; FIG. wherein a voltage bias between each addressable electrode and the counter electrode determines at least one of a size, shape and density of an electrostatically activated toner patch, having a solid concentration of 10-50%, that is deposited on one of the addressable electrode and the counter electrode. There's a problem loading this menu right now. For example, FIG. Then, toner patches are applied to the photoreceptor 23 by three toner applicators 21-6, 21-7 and 21-8. The controller 27 can also be implemented using a plurality of separate dedicated programmable integrated or other electronic circuits or devices, e.g., hardwired electronic or logic circuits such as discrete element circuits or programmable logic devices. $5.99 #34. 7; FIG. An image forming apparatus using a contact electrostatic printing process, comprising: at least two toner applicators that deposit toner having a high solid concentration of 10 to 50% on a support; an image support, at least two toner layers overlapping on the image support; and.

Accordingly, a developed toner image is formed on the photoreceptor 23, which is transferred to an image bearing member 28. Bcway Plastic Spray Bottle, 16oz Trigger Sprayer for Cleaning Solutions, 3 Modes (SPRAY & STREAM & OFF) Refillable Empty Mist Spray Bottle for Essential Oils, Air Freshening & Gardening. That is, the entire toner mass of a composite toner layer, or custom color cake, corresponding to the image area of the latent image, is developed into the image portion of the toner image. However, the CEP apparatus 100 shown in FIG. Several of the elements of a CEP apparatus are similar to, if not the same as, corresponding elements in the conventional liquid and/or solid toner electrostatic printing systems.

that are electrically insulated from each other. However, other configurations are possible.

all of the toner in the toner layer, or a predefined portion, or slice, of the entire layer, is transferred to the image roll 22. 1 CEP apparatus 100, there preferably is no image or toner layer conditioning between each toner application. In this embodiment, an electrostatic charge pattern is formed on the photoreceptor 23 by a first electrostatic charge pattern generator 24-1. Take full advantage of our site features by enabling JavaScript. The contact electrostatic printing device of claim 14, wherein the depositing means comprises addressable applicator means for depositing toner layers of at least one of a desired shape, size, density and location on a support.

at least one electrostatic charge pattern generator that generates a charge pattern on the photoreceptor before toner is applied to the photoreceptor. In particular, the invention relates to methods and apparatus for enhancing the capabilities of such printing systems to provide on-demand custom colors. 4 is a side view of the second embodiment of an addressable toner applicator in accordance with the invention; FIG. In one aspect of the invention, two or more toner layers are deposited on the image support to form a custom color toner layer before the custom color toner layer is acted on by at least one electrostatic charge pattern to form a custom color toner image. BAR5F Applicator Bottle with Angled Tip 8.5 ounce (Pack of 2), Driew Applicator Bottle with Angle Tip Pack of 2, 5oz Empty Scale Applicator Bottle for Hair Salon Coloring Dyeing with Slant Tip, BAR5F Twist Top Applicator Bottle, 8 ounce (Pack of 3), Root Comb Applicator Bottle, 6 ounce with graduated scale, Hair Coloring, Dye and scalp treament essential (Pack of 1), BAR5F Twist Top Applicator Bottle, 8 ounce (Pack of 2), BAR5F Applicator Bottle 4 ounce, Tip without the Hole, Cut the Top for Custom Applications of Your Choice (Pack of 2), Root Comb Applicator Bottle, 6 ounce with graduated scale, Hair Coloring, Dye and scalp treament essential (Pack of 3). This invention relates generally to liquid developing material-based electrostatic latent image development, wherein a layer of liquid developing material is brought into contact with a latent image-bearing surface in the vicinity of an electric field for causing selective image-wise separation of the liquid developing material layer to produce a desired output image corresponding to the latent image. In one aspect of the invention, toner is applied to an intermediate support that transfers toner to the image support. For example, the color correction device could detect that a deposited custom color toner layer is not red enough and control the CEP apparatus 100 to deposit red toner on the custom color toner layer to achieve the desired color. Accordingly, the combined first and second toner images can contain toner portions or a toner image having yellow, blue and/or green colors. The method of claim 9, wherein the step of forming a plurality of toner layers comprises depositing at least one toner layer in at least one of a desired size, shape, density and location on the support. The DAME reusable applicator wins as it’s an easy entry point to eco-friendly products, especially if a tampon with an applicator is your preferred choice. That is, a toner layer, or cake, is formed by the toner applicator 21 and the toner layer is transferred in a block to the image roll 22 during creation of a toner layer on the image roll 22, i.e. 7 shows a desired final image to be printed by the CEP apparatus 100. Beginning of a dialog window, including tabbed navigation to register an account or sign in to an existing account. 15. Three toner applicators 21-1, 21-2 and 21-3 each apply a layer of toner on an outer surface of an image roll 22. Read our Cookie Policy.

forming an electrostatic latent image that acts on at least one of the toner layers. In this process, toner particle migration or electrophoresis is replaced by direct surface-to-surface transfer of a toner layer induced by image-wise fields. Free delivery from £30. The apparatus of claim 1, wherein the toner applicators are controllable to selectively deposit the toner layers in at least one of varying sizes, shapes, densities and locations on a support. Some electrostatic imaging systems operate in a manner wherein the latent image includes charged image areas for attracting developer material (so-called charged area development (CAD), or "write white" systems), while other printing processes operate in a manner such that discharged areas attract developing material (so-called discharged area development (DAD), or "write black" systems). In this embodiment, the toner is applied to the photoreceptor 23 after a charge pattern is formed on the photoreceptor 23.
