    摘要： A process for preparing an oxytitanium phthalocyanine hydrate crystal which, when dried at 100.degree. C. and 0.1 mmHg for 8 hours and then allowed to stand in air at room temperature for 12 hours, has a structural formula of TiOPc.multidot.(H.sub.2 O).sub.n, wherein Pc represents a phthalocyanine nucleus, and n represents a number of from 0.15 to 1, and elemental analysis values of C: 65.0 to 66.3%, H: 2.5 to 3.1%, and N: 18.5 to 19.3% is disclosed, which process comprises the steps of: mechanically grinding a mixture of oxytitanium phthalocyanine and an inorganic salt to convert the crystal form of the oxytitanium phthalocyanine to a crystal form showing a distinct peak in its X-ray diffraction pattern at a Bragg angle (2.theta..+-.0.2.degree. ) of 27.3.degree. and treating the resulting oxytitanium phthalocyanine crystal with a mixed solvent of water and a water-insoluble organic solvent. The oxytitanium phthalocyanine hydrate crystal obtained has doped therein a specific amount of water of crystallization and is stable in a solvent and also stable when used as an electrophotographic photoreceptor.
