Abstract

A cleaning apparatus includes a first cleaning roller, and a second cleaning roller. The first cleaning roller is contrived to contact to a circumferential surface against a moving member to be cleaned and to apply a bias to the member to be cleaned while rotating such that the circumferential surface of the first cleaning roller moves in a same direction as the member to be cleaned moves. The second cleaning roller is contrived to contact to the member to be cleaned after the member has been cleaned by the first cleaning roller and to rotate such that a circumferential surface of the second cleaning roller moves in a direction opposite a direction in which the member being cleaned moves.
