Charge generation layer in an electrophotographic imaging member

Abstract

An electrophotographic imaging member comprising a support substrate having a two electrically conductive ground plane layer comprising a layer comprising zirconium over a layer comprising titanium,a hole blocking layer, an adhesive layer comprising a copolyester film forming resin, an intermediate layer in contact with said adhesive layer, said intermediate layer comprising a film forming carbazole polymer, a charge generation layer comprising perylene or a phthalocyanine particles dispersed in a film forming polymer binder blend of polycarbonate and carbazole polymer, and a hole transport layer, said hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from said charge generation layer and transporting said holes through said charge transport layer.
