Disclosed herein is an electrophotographic imaging member comprising a substrate, a charge transport layer and an overcoat layer formed by combining a film forming binder and a hole transporting hydroxy triarylamine compound having at least one hydroxyl functional group that is linked to a ring carbon of an aryl group by an alkyl group having 1 to 12 carbon atoms and is capable of forming at least one of a chemical bond and a physical bond with the film forming binder. Also disclosed is an electrophotographic imaging member with an overcoat layer formed by combining a film forming polycarbonate binder, a hole transport material, a surface energy reducing silicone material comprising a crosslinkable acrylate monomer, and a solvent. Coatings and methods of forming imaging members also are disclosed.

Overcoat for electrophotographic imaging member and methods of making and using same

A photoconductor that includes, for example, a supporting substrate, a photogenerating layer, a charge transport layer, and an overcoat layer that contains a titanocene.

Overcoat containing titanocene photoconductors

A photoconductor that includes, for example, a supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport component, and wherein the charge transport layer contains a carbazole.

Carbazole containing charge transport layer photoconductors

An imaging member with a unique overcoat composition adapted for forming protective, scratch-resistant overcoats is disclosed. The overcoat composition comprises a binder component that includes particular proportions of a acrylated polyol and propylene glycol. The overcoat composition also comprises a transport agent and a crosslinking agent.

Imaging member

A photoconductor that includes, for example, a supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport component, and wherein the charge transport layer contains a pyrazine.

Provided is an imaging member such as photoreceptor comprising a substrate, a charge generation layer, a first charge transport layer, a second charge transport layer, and an optional overcoat layer. The first charge transport layer is formed from a first CTL formulation comprising an aromatic monoamine and a first polymeric film forming binder material. The second charge transport layer is formed from a second CTL formulation comprising aromatic diamine and a second polymeric film forming binder material. The imaging member has gained improved properties such as removal of anti-curl layer, desirable structural flatness, electrical properties, mechanical robustness, flexibility, longevity, and copy image qualities over extended use, among others.

Imaging member having first and second charge transport layers

An imaging member including a substrate; thereover a charge generating layer; thereover a first charge transport layer comprising a small molecule charge transport material and a polymeric component selected from the group consisting of polyarylamine polyester, polyacylamine, and mixtures and combinations thereof; and a second charge transport layer disposed over the first charge transport layer, the second charge transport layer comprising a small molecule charge transport material and a binder, wherein the second charge transport layer is free of polyarylamine polyester and polyacylamine.

Imaging members and process for preparing same

A photoconductor that includes, for example, a supporting substrate, a photogenerating layer, and at least one charge transport layer containing at least one charge transport component, and wherein the charge transport layer also contains a thiadiazole.

Thiadiazole containing charge transport layer photoconductors

A photoreceptor comprising a charge transport layer doped with a polyarylate polymer is provided. A charge transport layer is doped with about 0.1 to about 10.0% by weight, solids basis, of a polyarylate polymer, such as for example Ardel. Charge transport layers doped with a polyarylate polymer exhibit improved electrical performance in terms of lower Vand Vvalues.

Photoconductive imaging member

An imaging member is disclosed which includes a charge generating layer and a charge transport layer. The charge transport layer includes a first charge transport layer adjacent the charge generating layer and at least a second charge transport layer adjacent the first charge transport layer. Each charge transport layer includes a film forming polymer binder and a charge transport material dispersed therein. The first charge transport material has a composition which is the same or different than the second charge transport material and of a lower concentration. It may be selected from an aryl amine, aryl diamine, or combinations thereof. The combination has the effect of reducing charge deficient spots.

A photoconductor containing an optional supporting substrate, a photogenerating layer, and at least one silanol containing charge transport layer.

Photoconductor having silanol-containing charge transport layer

A charge transport layer for an imaging member comprising a charge transport material with a nitrogen molecular defense system not exhibiting early onset of charge transport layer fatigue cracking. The nitrogen molecular defense system includes attaching bulky organic groups to charge transport materials. The bulky groups aid in preventing recrystallization of the charge transport molecule and shield the nitrogen from molecular attack, such as by oxidation. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and outstanding print quality.

A photoconductive imaging member comprised of a photogenerating layer, and a charge transport layer containing a binder and a fluoropolymer generated by the free radical polymerization of a fluoroalkyl(methyl)acrylate and an alkyl(methyl)acrylate.
