<P>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor of which charge generating substance has no less high sensitivity than a Y type titanyl phthalocyanine pigment and also no humidity dependency of sensitivity, and an image forming apparatus using the electrophotographic photoreceptor. <P>SOLUTION: An electrophotographic photoreceptor comprises a photosensitive layer which includes a pigment containing at least either a titanyl phthalocyanine and (2R,3R)-2,3-butanediol adduct or the titanyl phthalocyanine and (2S,3S)-2,3-butanediol adduct, and the pigment of which D50 particle size is 100-300 nm and D10 particle size is 50-200 nm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
