Disclosed is an overcoated photoreceptor which has the intrinsic ability to charge in a dot Screen fashion. In one embodiment, the photoreceptor is comprised of a continuous blocking layer overcoated with a trigonal selenium injecting layer, which in turn is overcoated with a transport layer such as selenium, which selenium layer is optionally overcoated with a generating layer of selenium-tellurium and an optional top or overcoating layer of, for example, polyurethane. In another embodiment, an injecting layer of carbon or gold is overcoated with a blocking layer of a photoresist material. The blocking layer allows for the formation of an insulating dot pattern of a certain spatial frequency.
