ABSTRACT:
An electrophotographic photoreceptor is disclosed, comprising a substrate having thereon at least an electric charge generating layer and an electric charge transporting layer, characterized in that the electric charge generating layer is formed from a coating solution which is prepared by dispersing an electric charge generating material and an acid in a binder resin solution. Useful acids are inorganic acids, including hydrochloric acid, sulfuric acid, hydrobromic acid and phosphoric acid, and organic acids, including formic acid, acetic acid, propionic acid, butryric acid, lactic acid, benzoic acid and sulfonic acid. This material has an increased sensitivity and thus can be effectively used in copying machines.
