Laminated organic photosensitive material comprising an X-type nonmetal phthalocyanine in the charge generating layer

摘要

There is disclosed a laminated organic photosensitive material which comprises an electroconductive support, an undercoat, a charge producing layer and a charge transporting layer in sequence wherein the undercoat is composed of an alcohol soluble polyamide resin and wherein the charge producing layer contains X-type nonmetal phthalocyanine as a charge producing substance and a mixture of a vinyl chloride-etyhylene copolymer in an amount of 40-95% by weight and a vinyl chloride-vinyl acetate-maleic acid copolymer in an amount of 5-60% by weight based on the mixture as a binder resin for the layer.
