Amorphous and cocrystallized unsubstituted titanyl phthalocyanine-titanyl fluorophthalocyanine compositions, preparation methods, and electrophotographic elements utilizing the compositions. The method has the steps of: admixing crude titanyl phthalocyanine and crude titanyl fluorophthalocyanine to provide a pigment mixture; increasing the amorphousness of the pigment mixture as determined by X-ray crystallography using X-radiation characteristic of Cu K.alpha. at a wavelength of 1.541 .ANG. of the Bragg angle 2.theta. to provide an amorphous pigment mixture; contacting the amorphous pigment mixture with a non-crystallizing solvent.
