Reported here are novel submicron diameter crystals of titanium oxide phthalocyanine (TiOPc) and the electrophotographic properties of photoreceptors that employ them. The use of triether solvents such as diethylene glycol dimethylether and dimethoxy tetrahydrofuran produces five times smaller TiOPc crystals than the phase 3 TiOPc crystals produced in tetrahydrofuran. The photosensitivity of these smaller TiOPcs is as high as that of the tetrahydrofuran produced phase 3 TiOPc crystals, which have been a source for one of the most photosensitive charge generation materials used in electrophotographic photoreceptors.
