摘要

The photoconductive photosensitive member (2) and a charge retaining medium (1), which face one another at a predetermined interval, are exposed to light while a voltage is applied between them from an external power source (E). The discharge occurring in the exposed areas produces an electrostatic image on the charge retaining medium. The applied voltage is removed a predetermined time after a shutter is closed so that all the carriers generated in the member can be transferred to the medium. Thus the quantity of charge corresponding to an exposure quantity is stored in the charge retaining medium irrespective of the kind of the ' photoconductive member used. If the charge retaining medium or photosensitive member is charged in advance in this case, a positive image can be obtained with the external power source disconnected. Alternatively, the applied voltage may be removed after the photosensitive members are separate from the member on which an electrostatic charge image has been formed. The image is prevented from distortion.
