ABSTRACT:
An electrophotographic copying method, which comprises conducting each process of at least charging, exposing to light, developing and transferring, characterized in that the photoreceptor has at least an undercoat layer and a photosensitive layer on an electroconductive substrate, wherein the undercoat layer contains a semiconductive material having a band gap of at least 2.2 eV and a binder resin, the photosensitive layer contains at least a phthalocyanine compound as a charge-generation material, and image-formation is carried out from the first revolution of the photoreceptor.
