ELECTROSTATIC RECORDING APPARATUS AND METHOD

摘要

An electrostatic copying device including a donor roller for supplying a layer of toner and a photoreceptor drum and associated components for generating a latent image are operated in consort in a two-rotation cycle of operation under controlled condition. During the first rotation of the cycle of operation the photoreceptor is uniformly charged with a relatively low corona charge and the photoreceptor is used as a biased roller to make uniform the layer of toner placed on the donor roller. During the second rotation of the cycle of operation the latent image is generated and the latent image is developed using the uniformly made toner layer.
