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