Abstract
An electrophotographic imaging member is disclosed having an imaging surface adapted to accept a negative electrical charge, the electrophotographic imaging member comprising a metal ground plane layer comprising zirconium, a hole blocking layer, a charge generation layer comprising photoconductive particles dispersed in a film forming resin binder, 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.
