ABSTRACT:
Hydroxygallium phthalocyanine crystals are produced by reacting a gallium trihalide with phthalonitrile or diiminoisoindoline in a halogenated aromatic hydrocarbon solvent, treating the resulting halogenated gallium phthalocyanine with an amide solvent, and hydrolyzing the halogenated gallium phthalocyanine. The photoreceptor exhibits stabilized electrophotographic characteristics.
