    摘要： An electrophotographic imaging member is disclosed including a support substrate having a two layered 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, a charge generation layer comprising a perylene or a phthalocyanine, an intermediate layer over and in contact with the charge generation layer, the intermediate layer comprising a carbazole polymer and an optional charge transporting molecule, 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.

    摘要： An electrophotographic imaging member including a substrate, a charge generating layer, a charge transport layer including charge transporting molecules dispersed in a first polymer binder, and an overcoat layer including a triphenyl methane molecule dispersed in a second polymer binder, the second polymer binder being soluble in a solvent in which the first polymer binder is insoluble and the charge transport layer being substantialy free of any triphenyl methane molecules. The overcoat layer may also contain a charge transport molecule. The device may also include any suitable optional charge blocking, adhesive and other sub layers. This electrophotographic imaging member is fabricated by forming on a charge generating layer a first coating comprising charge transporting molecules dispersed in a solution of a first polymer binder dissolved in a first solvent, drying the coating to remove the solvent to form a substantially dry charge transport layer, forming on the charge transport layer a second coating comprising triphenyl methane molecules and charge transporting molecules dispersed in a solution of a second polymer binder dissolved in a second solvent, the first polymer binder being insoluble in the second solvent and the charge transport layer being substantialy free of any triphenyl methane molecules, and drying the second coating to remove the second solvent to form a substantially dry overcoat layer. This electrophotographic imaging member may be utilized in an electrophotographic imaging process.
