ABSTRACT:
An electrophotographic copying apparatus includes a photosensitive member in the form of an endless belt having images of the document formed on its surface in a predetermined position by exposure to an optical image of the document while travelling. The photosensitive member has a peripheral length which includes a reserve when the photosensitive member is trained over a group of rollers without loosening, and is divided into a first section including a predetermined exposing position, a third section and a fourth section connected at one end thereof to opposite ends of the first section and accommodating the reserve in length by loosening the belt, and a second section connected to opposite ends to the other end of the third and fourth sections. At least one copying processing means other than a scanning and exposing means is located in the vicinity of the second section. The movement of the photosensitive member is controlled in such a manner that it is alternately moved in the first section at a high constant speed when scanning and exposing are carried out at a low constant speed or stopped when the scanning and exposing means is restored to its original position, and it is constantly moved in the second section at a constant speed intermediate between the two speeds at which it is alternately moved in the first section.
