Abstract: An improved photoelectrophoretic imaging method is disclosed wherein the imaging suspension is brought into contact under a first electrical field with a blocking layer having a coating which interacts, in the dark, with the pigment particles of the imaging suspension so as to provide a uniformly charged imaging suspension. The imaging suspension is then exposed to appropriate electromagnetic radiation while under a second electrical field. A second blocking layer, free of said coating is employed to produce positive and negative images.

Abstract: A process for generating two-color images comprising: (1) charging an imaging member in an imaging apparatus; (2) creating on the member a latent image comprising areas of high, intermediate, and low potential; (3) providing an electrode having a potential within about 100 volts of that of the intermediate potential, enabling generation of an electric field and a developement zone between the imaging member and the electrode; and (4) developing the latent image by introducing into the development zone a liquid developer composition containing first toner particles of one color and second toner particles of another color, the particles being dispersed in a liquid medium, wherein the second toner particles are attached to the high potential and the first toner particles are attracted to the low potential. Another embodiment of the invention resides in a process for generating two-color images, comprising: (1) creating on an imaging member in an imaging apparatus a latent image comprising areas of positive, negative, and substantially no potential; (2) providing an electrode having a potential within about 100 volts of that of the area of substantially no potential, enabling the generation of an electric field and a development zone between the electrode and the imaging member; and (3) developing the latent image by introducing into the development zone a liquid developer composition containing first toner particles of one color and second toner particles of another color, the particles being dispersed in a liquid medium, wherein the second toner particles are attracted to the positive potential and the first toner particles are attracted to the negative potential.

Abstract: An improved photoelectrophoretic imaging method is disclosed wherein a blocking layer is provided with a coating which interacts, in the dark, with the pigment particles of the imaging suspension so as to provide a uniformly charged imaging suspension upon exposure of the suspension to an electric field. The coating material occupies at least a substantially equal position in the Dark Charge Injection Series as any pigment in the imaging suspension. Subsequent or simultaneous electromagnetic radiation to which at least some of the particles are sensitive then results in the formation of optically positive and negative images.

Abstract: In an electrophotographic printing machine, a layer of insulating fluid containing micelles is positioned over a photoreceptor. The micelles are migrated onto the surface of the photoreceptor. The photoreceptor is exposed to inject charge carriers into the insulating fluid and selectively neutralize micelles to form an electrostatic latent image. The latent image is transferred to a dielectric surface and developed.

Abstract: An automatic development control for use in an electrophotographic apparatus. The control includes a pair of substantially planar members forming a channel therebetween through which developer flows. One of the members is constructed such that an electrostatic charge pattern is periodically formed on the surface thereof, the charge pattern being developed by the attraction of toner thereto which toner has a charge opposite to that forming the charge pattern. The member on which the developed charge pattern is formed includes a uniform, transparent conducting substrate covered with a transparent insulating layer on top of which is deposited a set of spaced-apart, opaque and electrically conducting fingers. Thus, the one member includes alternate opaque and transparent areas. By grounding the electrically conducting fingers which are all interconnected and by driving the substrate alternately positive and negative, toner is deposited on the transparent areas during the application of one half cycle of voltage and during the following half cycle the toner is deposited on the opaque fingers and scavenged from the transparent areas. The optical density of the toner deposited is directly related to the toner concentration in the developer. The one member then forms part of the toner concentration control.
