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

A charge transport layer composition for a photoreceptor includes at least a binder, at least one arylamine charge transport material, e.g., N,N'-diphenyl-N,N&#x2032;-bis(3-methylphenyl)-(1,1&#x2032;-biphenyl)-4,4&#x2032;-diamine, and at least one polymer containing carboxylic acid groups or groups capable of forming carboxylic acid groups. The charge transport layer forms a layer of photoreceptor, which also includes an optional anti-curl layer, a substrate, an optional hole blocking layer, an optional adhesive layer, a charge generating layer, and optionally one or more overcoat or protective layers.

Photoreceptor charge transport layer composition

A photoconductive imaging member comprised of an optional supporting substrate, a hole blocking layer thereover, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer is comprised of a pyrolyzed polyacrylonitrile.

Disclosed is a process for treating particles of selenium alloy to reduce fractionation when the particles are subsequently vacuum evaporated onto a substrate which comprises (1) heating particles of an alloy of selenium and an alloying component selected from the group are exposed to oxygen; (2) exposing the particles to water vapor; and (3) subjecting the particles previously exposed to oxygen and water vapor to a vacuum. Also disclosed is a process which comprises (1) providing particles of an alloy of selenium and an alloying component selected from the group consisting of tellurium, arsenic, and mixtures thereof; (2) forming selenium oxide on the surfaces of the particles; (3) converting the selenium oxide on the particle surfaces to selenious acid; and (4) removing the selenious acid from the particle surfaces.

Process for controlling alloy fractionation

A process for the preparation of chalcogenide alloys which comprises crystallizing a chalcogenide alloy, grinding and pelletizing the crystallized product, and evaporating the alloy on, for example, a supporting substrate to form a photoreceptor.
