A solution is proposed to the well-known problem of the mechanical weakness, particularly brittleness, of cast layers of poly(N-vinylcarbazole), polyvinyl pyrene, and similar hole transport polymers used in xerographic photoreceptors. The idea is to reinforce the cast film by drawn fibers of an active transport dielectric, such as PVK, so as to form a well-bonded composite film having improved flexibility and tensile strength without the sacrifice of electrical transport properties.
