OXYTITANIUM PHTHALOCYANINE CRYSTAL

摘要

A photoreceptor for electrophotography comprises a photosensitive layer containing an effective amount of oxytitanium phthalocyanine crystal having strong peaks at 9.6.degree., 24.2.degree. and 27.3.degree. and weak and broad peaks at approximately 11.6 .degree., 13.5.degree. , 14.3.degree. and 18.1.degree. in Bragg angle 2.theta. ~0.2.degree. by cuK.alpha. characteristic X-ray diffraction, and an exothermic peak at 266.degree.C in differential scanning calorimetry. The oxytitanium phthalocyanine crystal has a small grain size and a high stability and thephotoreceptor has a high photosensitivity to light having a long wavelength.
