Abstract

See full text

An image forming apparatus includes a rotatable image bearing member, a developing member to develop an electrostatic latent image at a developing portion, a transfer member to transfer a developer image to a recording member at a transfer portion; and a brush provided with a plurality of base materials contacting the image bearing member at downstream of the transfer portion and upstream of the developing portion in a rotational direction of the image bearing member. The developer remaining on the surface of the image bearing member is collected in the developing portion. An average distance between base materials of the brush with respect to a rotational axis direction of the image bearing member is larger than an average particle diameter of the developer, and is equal to or less than a length corresponding to a special frequency visually recognizable by a user when the image formed by the image forming apparatus is observed by the user.
