ABSTRACT:
Dichlorotin phthalocyanine crystals having distinct diffraction peaks at (i) 8.7.degree., 9.9.degree., 10.9.degree., 13.1.degree., 15.2.degree., 16.3.degree., 17.4.degree., 21.9.degree. and 25.5.degree., or (ii) 9.2.degree., 12.2.degree., 13.4.degree., 14.6.degree., 17.0.degree. and 25.3.degree. of the Bragg angle (2.theta..+-.0.2) to a CuK.alpha. characteristic X-ray; a method of preparing dichlorotin phthalocyanine crystals having the strongest diffraction peak at 28.2.degree. in the range of from 25.degree. to 30.degree. of the Bragg angle (2.theta..+-.0.2) in an X-ray diffraction spectrum; and an electrophotographic photoreceptor comprising an electroconductive support having thereon a light-sensitive layer containing the dichlorotin phthalocyanine crystals having distinct diffraction peaks at the particular angles or the dichlorotin phthalocyanine crystals prepared by the method.
