Abstract: METHOD FOR DEVELOPMENT OF A LATENT ELECTROSTATIC IMAGE EMPLOYING A DONOR MEMBER ADAPTED TO RETAIN TONER ON ITS SURFACE AND HAVING A NUMBER OF PROCESSING STATIONS ARRANGED AROUND ITS PERIPHERY THE DONOR MEMBER HAS A CORONA-CHARGEABLE DIELECTRIC SURFACE AND IS POSITIONED SO THAT A PORTION OF ITS PERIPHERY PASSES THROUGH TONER IN A VIBRATING RESERVOIR. THE RESERVOIR IS MAINTAINED AT A POTENTIAL LOWER THAN THE CHARGED DONOR MEMBER. THE TONER IS TRIBOELECTRICALLY CHARGED IN THE VIBRATING RESERVOIR VIA A COATING ON THE INSIDE OF THE RESERVOIR CAPABLE OF SO CHARGING THE TONER AND SAID TONER IS ATTRACTED TO THE DIELECTRIC SURFACE OF THE DONOR WHICH IS CORONA CHARGED OPPOSITELY TO THAT OF THE TONER.

Abstract: 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.
