Abstract:
1. 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 wherein said at least one charge transport component is comprised of aryl amine molecules of the formula wherein X and Y are each independently alkyl, alkoxy, aryl, or a halogen, 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 monohalobenzene; and wherein said photogenerating layer contains a thiophosphate represented by wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each independently represents alkyl containing from 1 to about 20 carbon atoms; cycloalkyl containing from 6 to about 26 carbon atoms; and aryl, alkylaryl or arylalkyl containing from about 6 to about 50 carbon atoms.
