Abstract:
A cleaning device for an intermediate transferring member, comprising: a first cleaning roller that is placed so as to rotate while being made in contact with a surface of the intermediate transferring member; a first bias-applying device that applies a bias voltage to the first cleaning roller; a second cleaning roller that is placed so as to rotate while being made in contact with the surface of the intermediate transferring member on a downstream side from the first cleaning roller in a surface-moving direction of the intermediate transferring member; and a second bias-applying device that applies a bias voltage having a polarity different from that of the bias voltage applied by the first bias-applying device to the second cleaning roller, wherein the first cleaning roller is a brush roller, and the second cleaning roller is a foam roller having a foam layer on a surface thereof, with a cell wall face in the foam layer having an opening ratio in a range of 3% or more to 50% or less, and an image-forming apparatus equipped with said cleaning device for an intermediate transferring member.
