US Classification:

430 583, 430 584, 430 5865, 430 5875, 430 588, 430 596

Abstract:

An imaging member having a charge transport layer with multiple regions is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein at least the top or uppermost transport layer comprises 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 of the same or different compounds from that included in the top or additional charge transport layer(s). The charge transport compound present in each layer may be 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.
