Abstract
Gallium phthalocyanine halide crystals wherein a part of the crystals are changed into hydroxygallium phthalocyanine is disclosed. A method for preparing gallium phthalocyanine halide crystals wherein gallium phthalocyanine halide crystals are brought into contact with water and a part of the crystals are changed into hydroxygallium phthalocyanine is also disclosed. An electrophotographic photoreceptor formed by laminating at least a charge generating layer and a charge transporting layer successively on a conductive support wherein the charge generating layer contains gallium phthalocyanine halide crystals An which a part of the crystals are changed into hydroxygallium phthalocyanine is also disclosed.
