Abstract:
When secondary-transfer residual toner adheres to a brush member, the secondary-transfer residual toner is concentrated on an end of the brush member and it is difficult to uniformly charge the secondary-transfer residual toner. The secondary-transfer residual toner can be recovered to the roots of conductive fibers of the brush member by satisfying the relationship Rb≧Ri, where Rb (Ω) is a resistance value of the brush member and Ri (Ω) is a resistance value of an intermediate transfer member in an area where the intermediate transfer member is in contact with the brush member.
