    摘要: A new crystalline form of oxytitanium phthalocyanine is characterized by main peaks specified by Bragg angles (2.theta..+-.0.2 degrees) of 7.4 degrees, 10.2 degrees, 12.5 degrees, 15.0 degrees. 16.3 degrees, 18.3 degrees, 22.4 degrees, 24.2 degrees, 25.2 degrees and 28.5 degrees in X-ray diffraction pattern based on CuK.alpha. characteristic X-rays. The oxytitanium phthalocyanine is formed by treating amorphous oxytitanium phthalocyanine with a solvent selected from the group consisting of monohydric alcohols having at least two carbon atoms, cellosolves, diethylene glycol monoethers and diacetone alcohol. The oxytitanium phthalocyanine is useful as a charge generating material for providing an electrophotographic photosensitive member, which shows a stably high sensitivity to long wavelength light.
