Multilayered photoreceptor with dual underlayers for improved adhesion
and reduced micro-defects
摘要:
An electrophotographic imaging member having an imaging surface adapted to accept a negative electrical charge, the electrophotographic imaging member having a two electrically conductive ground plane layers including a layer including zirconium over a layer including titanium, a siloxane hole blocking layer, an adhesive layer including a polyarylate film forming resin, an intermediate layer over and in contact with the adhesive layer, the intermediate layer including a carbazole polymer, a charge generation layer comprising benzimidazole perylene particles dispersed in a film forming resin binder of poly(4,4'-diphenyl-1,1'-cyclohexane carbonate), and a hole transport layer, the 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 the charge generation layer and transporting the holes through the charge transport layer.
