ABSTRACT:
An electrophotographic apparatus comprises an electrophotographic photosensitive member and means for applying an electrophotographic cycle to the photosensitive member. The electrophotographic cycle includes charging, image exposure, toner development, toner transfer, remaining toner cleaning, and exposure for erasing remaining electric charge. The electrophotographic cycle application means includes abrasion means. By setting the abrasion function of the abrasion means to provide an abrasion of the surface layer of the photosensitive member at a rate of 250 .ANG.or more per 1000 electrophotographic cycles applied to the photosensitive member, the deterioration of image quality such as image-flow and fading of images caused by succession of electrophotographic cycles is effectively prevented particularly with respect to a photosensitive member with a small diameter.
