ABSTRACT:
The disclosure describes an electrophotographic copying process for reversal development using a laminate-type electrophotographic photoreceptor having laminated on an electroconductive support a charge generation layer containing a phthalocyanine compound and a charge transport layer, and capable of forming plural copies of image, comprising at least charging step, image exposing step, developing step, transferring step and charge erasing step by light, wherein the charge erasure by light is not conducted in image formation by the first rotation of photoreceptor and is conducted in image formation by the second and succeeding rotations of photoreceptor.
