ABSTRACT:
A brush contact charger charges a photosensitive drum of an image forming apparatus adopting an electrostatic recording system, and has a body having a brush for contacting a photosensitive drum and then charging the photosensitive drum, a reciprocating portion for reciprocating the body perpendicularly with respect to the proceeding direction of the photosensitive drum, and a guide member for supporting the body while guiding the reciprocal movement of the body. The charger charges the surface of the photosensitive drum while moving at a right angle with respect to the proceeding direction of the photosensitive drum and charges the surface of the photosensitive drum to an electrical potential having a nearly uniform distribution.
