A method for obtaining multiple copies from apparatus including an electrophotographic member of the type in which the latent image is represented by charge not removed when toner is applied and thereafter transferred. The electrophotographic member with its latent image is repeatedly subjected to toning and transfer to respective multiple receptors without intervening charge and exposure. This may be done until the desired number of copies is made or until the image quality deteriorates by reason of dark decay. If additional copies are desired the electrophotographic member is again charged and exposed and thereafter toned and the image transferred repeatedly without intervening additional charge and exposure. Apparatus for effecting the method above and providing structure for carrying out the described steps include other functions such as automatically sensing quality and responding to a condition which requires a new cycle of charge and expose.
