A layered photoconductive imaging member comprised of a supporting substrate, a photogenerating layer and a charge transport layer, and wherein the photogenerating layer contains Type IV titanyl phthalocyanine obtained by a process which comprises the addition of an oxytitanium phthalocyanine containing a mixture of Type I and Type II titanyl phthalocyanine polymorphs, or a substantially pure Type II titanyl phthalocyanine polymorph to a solvent comprised of a trihaloacetic acid and an alkylene halide; adding the resultant solution to a mixture which enables precipitation of Type X oxytitanium phthalocyanine; separating the Type X oxytitanium phthalocyanine from the solution; and thereafter subjecting the Type X oxytitanium phthalocyanine obtained to treatment with a halobenzene, followed by the separation of the said Type IV oxytitanium phthalocyanine.
