    • A photoconductor that includes a supporting substrate, and an active layer in contact with the substrate, and which active layer contains a photogenerating pigment of a titanyl phthalocyanine, at least one charge transport component, and a mixture of a metal oxide and a chelating agent, where the titanyl phthalocyanine is prepared by dissolving a Type I titanyl phthalocyanine in a solution comprising a trihaloacetic acid and an alkylene halide; adding the resulting mixture of the dissolved Type I titanyl phthalocyanine to a solution comprising an alcohol and an alkylene halide thereby precipitating a Type Y titanyl phthalocyanine; and treating the Type Y titanyl phthalocyanine with a monohalobenzene to form Type V titanyl phthalocyanine.
    • 一种感光体,包括支撑衬底和与衬底接触的活性层,并且该活性层含有钛酞菁的光生色素,至少一种电荷传输组分和金属氧化物和螯合剂的混合物, 其中钛酞菁通过将I型氧钛酞菁溶解在包含三卤代乙酸和亚烷基卤的溶液中而制备; 将所得的溶解的I型氧钛酞菁的混合物加入到包含醇和亚烷基卤的溶液中,从而沉淀Y型氧钛酞菁; 并用单卤代苯处理Y型钛酞菁以形成V型氧钛酞菁。
