Abstract
A photoconductor containing an optional supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport component wherein the at least one charge transport component is comprised of aryl amine molecules of the formulawherein X and Y are each independently alkyl, alkoxy, aryl, a halogen, and wherein the photogenerating layer contains a titanyl phthalocyanine prepared by dissolving a Type I titanyl phthalocyanine in a solution comprising a trihaloacetic acid and an alkylene halide; adding the mixture comprising 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 monohalobenzene.
