摘要： Disclosed is an electrophotographic photoreceptor having a protective overcoat layer including a polyol binder; a hole transport material; a curing agent; and a surface-treated tin oxide particle filler. Also disclosed is a process for forming a photoreceptor that includes providing a photoreceptor substrate; applying a charge generating layer; applying a charge transport layer; and applying a protective overcoating layer over the substrate; such that the protective overcoat layer includes a polyol binder; a hole transport material; a curing agent; and a surface-treated tin oxide particle filler. Also included is a method of forming an image, including the disclosed photoreceptor.

摘要： A high quality hole transport material of a substituted biphenyl diamine, such as N,N,N′N′-tetra(4-methylphenyl)-(1,1′-biphenyl)-4,4′-diamine, where each X is independently selected from —H, alkyl(-CnH2n+1), where n is from 1 to about 10 such as from 1 to about 5 or from 1 to about 6, aralkyl and aryl groups, the aralkyl and aryl groups having, for example, from about 5 to about 30, such as about 6 to about 20 carbon atoms, where the purity of the hole transport material is from about 80 percent to about 100 percent, and when incorporated into a photoreceptor, the photoreceptor discharges from about 85% to about 100% of its surface potential in from 0 to about 40 milliseconds upon being subjected to xerographic charging and exposure to radiant energy of from about 1 ergs/cm2 to about, 5 ergs/cm2. Also disclosed is a photoreceptor containing the same.
