Claims24
A layered photoconductive imaging member consisting essentially of a supporting substrate, a photogenerator layer of perylene photoconductive pigments dispersed in a resin binder mixture comprised of two polymers, and a charge transport layer wherein one polymer is a polyvinylcarbazole and the second polymer is a polycarbonate homopolymer.
A layered photoconductive imaging member comprised of a supporting substrate, a photogenerator layer comprised of benzimidazole perylene photoconductive pigments dispersed in a resin binder mixture of polyvinylcarbazole and polycarbonate homopolymer, and thereover a charge transport layer.
A layered photoconductive imaging member consisting essentially of a photoconductive layer comprised of perylene photoconductive pigments dispersed in a resin binder mixture of polyvinylcarbazole and polycarbonate homopolymer.
A process for improving the electrical characteristics of imaging members which comprises adding to the photogenerator layer of such members a binder mixture of polyvinylcarbazole and a polycarbonate homopolymer.
A layered photoconductive imaging member comprised of a supporting substrate, a photogenerating layer comprised of perylene photoconductive pigment, and top charge transport layer wherein the improvement resides in selecting for the perylene photoconducting pigments, a resin binder mixture of a polyvinylcarbazole and a polycarbonate homopolymer.
