Abstract
An electrophotographic photoreceptor having a charge generation material is disclosed. The charge genaration material is mixed crystals of a titanylphthalocyanine and a vanadyl phtalocyanine, which have a characteristic peak at a Bragg angle (2.theta.) of 27.2.+-.0.2.degree. in an X-ray diffraction spectrum with a Cu-K .alpha. ray (wave length: 1.541 .ANG.) and having other specific physical property. The photoreceptor is suitably used in a printer or photocopying machine.
