ABSTRACT:
The subject application provides for a composition crystal comprising a phthalocyanine compound and an asymmetric phthalocyanine wherein a part of benzene ring in phthalocyanine structure is substituted with naphthalene ring, pyridine or pyrazine ring, is stable against crystal transfer such as agglomeration, precipitation, crystal growth, crystal habit transfer and crystal electric potential, and has good electric properties such as good sensitivity. When this composition crystal is used as a charge generation material in an electrophotographic receptor, the electrophotographic photoreceptor shows good sensitivity and good image quality without noise.
