ABSTRACT OF THE DISCLOSURE The invention provides an electrophotographic device by which the surface potential of a photosensitive member is substantially uniformalized at the time of termination of the photocopying process by rotating through one revolution the photosensitive member after completion of the copying process and subjecting the photosensitive member to A.C. corona discharge or light exposure. Moreover, a reflecting mirror and an in-mirror lens are integrally rotated so as to adjust the light path length to obtain the most effective exposure. Furthermore, the ratio of width of the central portion and of both end portions of the slit for exposure can be varied to obtain a uniform and effective exposure.
