Abstract

An electrophotographic imaging member including an electrophotographic imaging member having an imaging surface adapted to accept a negative electrical charge, the electrophotographic imaging member including a substrate, a siloxane hole blocking layer, an adhesive layer including a uniform blend of polyarylate film forming resin and a polyester film forming resin, a charge generation layer including hydroxygallium phthalocyanine particles dispersed in a film forming resin, 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.
