Abstract
A photosensitive material for electrophotography comprises a conductive support and a photosensitive layer formed on the conductive support, the photosensitive layer being made of X-type metal-free phthalocyanine, a resin binder, and an essential additive effective for improving electrophotographic or photosensitive characteristics or durability in repeated use wherein the X-type metal-free phthalocyanine is dispersed in the resin binder partly in a molecular state and partly in a particulate state. The essential additive includes electrolytically polymerized products, certain kinds of dyes, silane or polysilane compounds, hole and electron transport substances, titanyl or vanadyl phthalocyanine, electron acceptors, perylene compounds, amine derivatives, amino compounds, zinc oxide or the like.
