ABSTRACT:
A layered photoconductive imaging member comprised of a supporting substrate, a photogenerating layer comprised of titanyl phthalocyanine photogenerating pigments and thereover a charge transport layer, and wherein said photogenerating pigments are prepared by a process which comprises the formation of a slurry comprised of dihalotitanium phthalocyanine in a mixture comprised of a trihaloacetic acid and an alkylene chloride; adding the resultant slurry to a mixture of an aliphatic alcohol and water enabling hydrolysis whereby Type X oxytitanium phthalocyanine is obtained; separating the Type X oxytitanium phthalocyanine from the slurry; and thereafter subjecting the Type X oxytitanium phthalocyanine obtained to treatment with a halobenzene, followed by the separation of Type IV oxytitanium phthalocyanine photogenerating pigments.
