    摘要: A method for preparing hydroxygallium phthalocyanine crystals wherein hydroxygallium phthalocyanine crystals having distinct diffraction peaks at 7.0.degree., 13.4.degree., 16.6.degree., 26.0.degree. and 26.7.degree. of the Bragg angle (2.theta..+-.0.2.degree.) with respect to CuK.alpha. characteristics X-ray in the X-ray diffraction spectrum are crystal-transferred by solvent treatment. The crystals after crystal-transfer have distinct diffraction peaks at (i) 7.7.degree., 16.5.degree., 25.1.degree. and 26.6.degree., (ii) 7.9.degree., 16.5.degree., 24.4.degree. and 27.6.degree., (iii) 7.0.degree., 7.5.degree., 10.5.degree., 11.7.degree., 12.7.degree., 17.3.degree., 18.1.degree., 24.5.degree., 26.2.degree. and 27.1, (iv) 7.5.degree., 9.9.degree., 12.5.degree., 16.3.degree., 18.6.degree., 25.1.degree. and 28.8.degree. or (v) 6.8.degree., 12.8.degree., 15.8.degree. and 26.0.degree. of the Bragg angle (2.theta..+-.0.2.degree. C.) with respect to CuK.alpha. characteristics X-ray in the X-ray diffraction spectrum. An electrophotographic photoreceptor having a light-sensitive layer on a electroconductive substrate wherein the light-sensitive layer contains at least one of the hydroxygallium phthalocyanine crystals.
