Abstract
An image-forming apparatus includes an image-bearing member supporting a toner image; a transfer roller that rotates in contact with the image-bearing member so as to transfer the toner image to a recording material; first and second cleaning rollers, each having a brush provided on a circumferential surface thereof so as to electrostatically recover toner deposited on the transfer roller while rotating in contact therewith; a recovery roller that rotates in contact with the first and second cleaning rollers to electrostatically recover the toner therefrom; and a blade-like removing member that comes in contact with the recovery roller so as to remove the toner therefrom.
