To provide an electrophotographic photoreceptor having enough adhesion property which can maintain a stable potential in a copying machine even when the photoreceptor is repeatedly used for a long time.

This electrophotographic photoreceptor has at least a charge producing layer and a charge transfer layer successively formed on a conductive base body. The charge producing material in the charge producing layer consists of one or more kinds of trisazo pigments and/or bisazo compds. The charge transfer layer contains phthalocyanine pigments (preferably titanylphthalocyanine compds. or nonmetal phthalocyanine compds.).
