ABSTRACT:
A novel phthalocyanine mixed crystal comprising a dihalogenotin phthalocyanine and a halogenogallium phthalocyanine and an electrophotographic photoreceptor containing the same are disclosed. The phthalocyanine mixed crystal preferably has an intense X-ray diffraction peak at a Bragg angle (2.theta..+-.0.2.degree.) of 26.9. The phthalocyanine mixed crystal is useful as a charge generating material which provides an electrophotographic photoreceptor excellent in sensitivity, stability on repeated use, and environmental stability.
