PURPOSE: To provide a mixed oxytitaniumpthalocyanine crystal suited to produce a highly sensitive electrophotographic photoreceptor excellent in stability in repeated use and environmental stability, a process for producing the same, and a highly sensitive electrophotographic photoreceptor excellent in stability in repeated use and environmental stability. n CONSTITUTION: The title mixed crystal comprises oxytitaniumphthalocyanine and at least one hydroxymetal phthalocyanine. The central metal of the hydroxymetalphthalocyanine is selected from among aluminum, gallium, indium, silicon, germanium and tin. The mixed crystal is useful as a charge generator of an electrophotographic photoreceptor. n COPYRIGHT: (C)1992,JPO&Japio |
