Abstract
Disclosed is an electrophotographic imaging member that includes a substrate, a unitary electrophotographic insulating layer and a continuous phase having a transparent film forming polymer, the polymer phase having a surface facing away from the substrate, the surface facing away from the substrate contains imbibed dye molecules. The electrophotographic imaging member is prepared by subliming or vaporizing at least one sublimable or vaporizable dye on and into the surface of the layer facing away from the substrate. The invention also includes methods of forming multicolored or other images with this electrophotographic imaging member.

An electrophotographic imaging method comprising providing an imaging member comprising a substrate, a unitary electrophotographic insulating layer which is electrically insulating in the dark and electrically conductive when struck by activating radiation and a continuous, substantially transparent film forming polymer phase, said layer having a surface facing away from said substrate, said surface facing away from said substrate comprising imbibed dye molecules, providing said surface facing away from said substrate with at least two sets of internal preformed dye color filter patterns, one of said sets of internal preformed dye color filter patterns having a different colored dye from the other set, forming a uniform charge on said imaging member, exposing said uniform charge on said imaging member in a single step to a multi-colored light image to discharge said imaging member in the non-image areas and to form at least one electrostatic latent image corresponding to a first of said sets of internal preformed dye color filtered patterns and at least one electrostatic latent image corresponding to a second of said internal preformed dye color filtered patterns, developing said electrostatic latent image corresponding to said the first of said sets of internal preformed dye color filtered patterns with marking particles of a second color to form a second toned image, said first and second toned images being formed in a single pass, and transferring in a single step said first toned image and said second toned image to a receiving member, and affixing said toned images to a receiving member to complete an imaging cycle.
An electrophotographic imaging method comprising providing an imaging member comprising a substrate and a unitary electrophotographic insulating layer, said unitary electrophotographic insulating layer consisting essentially of a single charge generating layer and a single charge transport layer which is electrically insulating in the dark and electrically conductive when struck by activating radiation, said charge transport layer comprising a continuous, substantially transparent film forming polymer phase, said polymer phase having a surface facing away from said substrate, said surface facing away from said substrate defining an outer boundary of at least one region within said polymer phase, said region comprising a solid solution of from about 0.01 percent and about 5 percent by weight of an imbibed vaporized or sublimed dye molecules, based on the total weight of said film forming polymer in said region, and subjecting said imaging member to an imaging cycle comprising forming a uniform charge said imaging member exposing said uniform charge imaging member in a single step to a light image to form at least one electrostatic latent image, developing said latent image with marking particles to form a toned image, transferring said toned image to a receiving member in a single step, and fixing said toned image to said receiving member.
