    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 at least 50 percent by weight zirconium, a siloxane hole blocking layer, an adhesive layer comprising a polyacrylate film forming resin, 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.

    Abstract: A method of controlling variations in electrical characteristics in electrophotographic imaging devices by eliminating the effect of acidic or basic impurities in a photoconductive element. A solution of a weak acid or weak base and a conjugate salt of the weak acid and the weak base is incorporated into a layer of the photoconductive element. In a process for producing the photoconductive element, a substrate is coated with a first dispersion to form a charge generating layer, and then coated with a second dispersion to form a charge transporting layer, wherein there is incorporated in at least one of the first and second dispersions a solution of a weak acid or weak base and the conjugate salt of the weak acid and weak base in an amount effective to reduce variations in the dark development potential (VDDP) and background potential (VBG) characteristics of the imaging devices.
