摘要:
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′-bis(3-methylphenyl)-(2,2′-biphenyl)-4,4′-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.
摘要:
An imaging member having a charge transport layer is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein the upper or additional transport layer(s) comprise a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be the same or different from that included in the additional charge transport layers. The charge transport compound in one or more of the layers is dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.
