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 S 1  and 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 2 , a relationship of a linear speed ratio of S 2 /S 1 <1.0 is satisfied.

Claim (Index 1):
An image forming apparatus comprising:\n an image bearing member comprising a plurality of recess portions on a surface thereof and configured to rotate; a charging member configured to charge the image bearing member; an exposing device configured to expose the charged image bearing member to form an electrostatic image; a developing device configured to develop the electrostatic image formed on the image bearing member by toner; a transfer member configured to form a transfer portion between the transfer member and the image bearing member and transfer a toner image formed on the image bearing member onto a transfer material at the transfer portion; and a rubbing member disposed downstream of the transfer member and upstream of the charging member in a rotational direction of the image bearing member, formed from a rotary member including a surface layer formed from an elastic body, and 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, wherein the recess portions each have an opening portion whose maximum length in the rotational direction is 20 \u03bcm to 120 \u03bcm, and wherein, in a case where a linear speed of the image bearing member in the rubbing nip portion is S 1  and 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 2 , a relationship of a linear speed ratio of S 2 /S 1 <1.0 is satisfied.
