Abstract
An image forming apparatus includes an image bearing member, a charging member, an exposing device, a developing device, a transfer member, and a rubbing member. The image bearing member includes a plurality of recess portions on a surface thereof. The rubbing member is configured to come into contact with the image bearing member to form a rubbing nip portion between the rubbing member and the image bearing member. The recess portions each have an opening portion whose maximum length in the rotational direction is 20 μm to 120 μm. When a linear speed of the image bearing member in the rubbing nip portion is Sand a linear speed of the rubbing member in the same direction as the linear speed of the image bearing member in the rubbing nip portion is S, a relationship of a linear speed ratio of S/S<1.0 is satisfied.
