Abstract
A copying apparatus and method in which a single image of an original is utilized to form plural copies without degradation of the copy quality. A single rotatable drum is provided which has first and second photosensitive surfaces formed thereon. The image of the original is first scanned in response to which a latent image is formed the first photosensitive surface. This image is developed to form a primary toner image. As the drum is rotated through 180.degree., the primary toner image is repeatedly transferred to the second photosensitive surface so as to form repeatedly, upon developing, secondary toner images which are transferred to recording sheets. The same optical system is utilized for illuminating the first photosensitive surface with an image of the original and for transferring the primary toner image onto the second photosensitive surface.
