Abstract
An image forming apparatus includes a brush member that includes a fiber yarn and that can come into contact with a surface of an image bearing member at a downstream of a transfer member and at an upstream of a charging member in a rotation direction of the image bearing member. The image bearing member and the brush member are relatively movable to a first position at which a leading end of the fiber yarn separates from the surface of the image bearing member, and a second position at which the leading end of the fiber yarn comes into contact with the surface of the image bearing member. A relative approaching direction of the brush member to the image bearing member upon relative movement from the first position to the second position is a direction from a downstream side to an upstream side in the rotation direction.
