Patent ID: 7771909

Claim:
A photoconductor comprising an optional supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport component, and wherein said 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 said 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 said Type Y titanyl phthalocyanine with a monohalobenzene resulting in titanyl phthalocyanine with an X-ray diffraction pattern having characteristic diffraction peaks at a Bragg angle 2Θ±0.2° at about 9°, 9.6°, 24°, and 27.2°, and wherein said photogenerating layer is prepared from a dispersion of said titanyl phthalocyanine, a polymer binder, and a chlorinated solvent of at least one of 1,2-dichloroethane, 1,2-dichloropropane, or dichloromethane.
