Abstract
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.
