ABSTRACT:
An electrophotographic copying apparatus utilizing a rotatable drum having a photosensitive outer circumferential surface is disclosed herein along with its method of operation. In making copies of a given sheet of information, an electrostatic latent image corresponding to the information to be copied is formed on a circumferential segment of the drum surface and the image is developed by applying toner onto the image bearing segment of the drum surface. Thereafter, the applied toner is transferred to a blank sheet thereby forming the copy. Once one or more copies are made from a given electrostatic image, any applied but untransferred toner on the drum surface is moved onto a second circumferential segment, preferably by means of a pliant roller segment and preferably with the aid of electrostatic attraction. The toner accumulated on the second segment of the drum surface is then moved by the latter to a specific point and removed from the second surface segment. During this latter movement, the toner is electrostatically held in place on the second drum surface segment.
