ABSTRACT:
An electrophotographic photoreceptor comprising a photosensitive layer containing granular trigonal selenium which has a mean particle diameter of not more than 5 .mu.m and which has absorption peaks in the X-ray diffraction spectrum using CuK.alpha. characteristic X-rays at Bragg angles (2.degree..theta..+-.0.2.degree.) of 23.5.degree., 29.7.degree., 41.4.degree., and 45.4.degree., is disclosed, which has high photosensitivity and low residual potential, maintains its potential characteristics in a stable manner on repeated use, and exhibits sufficient photosensitivity even when applied to high-speed copying.
