Abstract
A cleaning apparatus includes a cleaning member having an abutment member being attached to a tip end portion of a support member. The support member includes a bent portion, an abutment-side support portion, and a fixed-side support portion. The abutment member abuts on a surface of an image carrying member. A point of fixation of the support member fixed to a fixing member is located downstream in a direction of movement relative to a normal at a point of abutment of the abutment member. With an angle of bending α at the bent portion being set to 90°<α<180°, the abutment-side support portion is curved in a form of a crest toward downstream in the direction of movement whereas the fixed-side support portion is curved in a form of a crest toward upstream in the direction of movement.
