Abstract

PURPOSE: To enable the damage on the surface of a photoreceptor to be prevented by moving a movable supporting member for holding the corona discharger thereby moving the corona discharger closer to or apart from the photoreceptor.
CONSTITUTION: An electrophotographic photosensitive drum 1 rotates in an arrow direction. A revolving shaft is fixed to the frame of the body of a copying machine and an arm 4 which is a supporting member for mounting a corona discharge is provided rotatably around this shaft. This arm 4 is provided with grooves 51, 52 to permit mounting of the corona discharger by inserting guide rails 24 for mounting the corona discharger therein. Further, the arm 4 is fixed on the side opposite from the revolving shaft to one part 6 of the arm of the copying machine by means of a knurled screw 7. When the corona discharger is pressed to the photoreceptor surface, the guide rollers 23 contact the nonimage parts of the photoreceptor to maintain a fixed distance between the guide rollers 23 and the corona discharging electrode this prevents the photoreceptor surface from being damaged at the time of mounting and dismounting the corona discharging electrode.
