Abstract:
A photoconductor for electrophotography comprising:(A) a conductive substrate; and(B) a photoconductive film on said conductive substrate, said photoconductive film consisting of a plurality of charge generation/transport layers from lower to upper, wherein each layer of said film(1) exhibits both a charge generation function and a charge transport function and(2) comprises both(i) a charge transport agent and(ii) a charge generation agent comprising a phthalocyanine compound described by the following formula: ##STR5## wherein M is TiO, 2H or Cu;each of R.sub.1, R.sub.2,R.sub.3, and R.sub.4 is independently hydrogen or a methyl group; andeach of k, l, m and n is independently 0, 1, 2 or 3; and wherein the concentration of said charge generation agent is higher in the upper layers versus the lower layers.
