Electrophotographic device

Abstract

Abstract PURPOSE:To remove well a remaining toner on a photosensitive body with a relatively low pressing force by pressing a blade, which has a tip part to be pressed to the photosensitive body, at an angle to the direction vertical to the driving direction of the photosensitive body. CONSTITUTION:A blade 19 has a tip part 18 pressed at an angle theta to a photosensitive body 10 having a required width W. An angle B made between the side face of the blade 19 and the driving direction of an arrow 16 of the photosensitive body 10 is increased according as the angle theta of inclination is increased. In case of B>90 deg., a digging-up action can be given to a component N of force; and even in case of B<90 deg., the pressing action is weak and toner retaining due to a component T of force acts effectively when the angle B is smaller. Thus, if the same blade 19 is used and the same pressing force P is applied, a more effective toner removing action is caused when the angle theta of inclination is made larger.
