ABSTRACT:
Disclosed is a method for producing an electrophotographic photoreceptor capable of repeated copying without one imagewise exposure for every one copying and which is superior in stability, sensitivity, resolution and tone reproduction. This method comprises converting to an insualtor, by irradiation with energy ray, any selected area of a surface of an electrophotographic photoreceptor comprising a conductive substrate, a carrier generation layer and a carrier transport layer composed mainly of a compound which is converted to an insulator by irradiation with energy ray.
