摘要:
An electrophotographic apparatus includes an electrophotographic photosensitive member, a charging device, an image exposure device, a developing device, a transfer device, and a control device. The control device stops rotation of the electrophotographic photosensitive member after a region of the electrophotographic photosensitive member, which region opposes the transfer device at the time when operation of the transfer device is stopped while the rotation of the electrophotographic photosensitive member is not stopped, passes, by at least one revolution, a position opposing the charging device which is running. The electrophotographic apparatus requires no idle rotation, makes high speed processing possible, suppresses negative and positive ghosting, and suppresses variations in electric characteristics and in image densities between first and second copying operations, thereby enabling images of high quality to be prepared quickly and simply.
