PROBLEM TO BE SOLVED: To provide a method for performing a satisfactory image formation from the first rotation of a photoreceptor in photographic copying method. SOLUTION: In an electrophotographic copying method for performing each process of at least charging, exposure, development and transfer to a photoreceptor, this photoreceptor has at least an undercoat layer and a photosensitive layer on a conductive support body, and the undercoat layer contains a semiconductive material having a band gap of 2.2eV or more and a binder resin, and the photoreceptor is formed of a photoreceptor containing at least phthalocyanine compound as charge generating material, and image formation is performed from the first rotation of this photoreceptor. |
