Abstract
An image forming apparatus including an image bearing member having a photosensitive layer and the surface including concave portions having a concave diameter of from 5 to 200 μm, an irradiation device that irradiates the surface of the image bearing member with light to form a latent electrostatic image thereon, a development device that develops the latent electrostatic image with a development agent containing toner to obtain a visualized image, a transfer device that transfers the visualized image to a transfer medium, a first cleaning brush to which a bias is applied with a polarity reverse to that of the toner remaining on the surface of the image bearing member after the visualized image is transferred, and a second cleaning brush to which a bias is applied with the same polarity as that of the toner remaining on the surface of the image bearing member.
