an image bearing member on which an electrostatic latent image is formed, and that is rotatable;

a charging member that charges the image bearing member and is rotatable;

a developing member that develops, as a developer image, the electrostatic latent image formed on the image bearing member;

a transfer member that transfers the developer image to a recording material; and

a brush member that includes a fiber yarn and has a flat shape, and that can come into contact with a surface of the image bearing member at a downstream side with respect to the transfer member and at an upstream side with respect to the charging member in a rotation direction of the image bearing member, wherein

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, and

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 of the image bearing member.
