Abstract:
A cleaning apparatus removes a toner and a paper dust remaining on an intermediate transfer belt. The pressure reducing member includes a fitting hole and an outer peripheral portion. The fitting hole is fitted to a rotation shaft of a rotation roller rotating at which the intermediate transfer belt is stretched. The outer peripheral portion is in a cam shape and has a diameter dimension larger than a diameter of the rotation roller. The outer peripheral portion is located around the fitting hole. The outer peripheral portion includes a first outer peripheral portion and a second outer peripheral portion. The first outer peripheral portion has a predetermined first radius and does not contact the supporting member when not reducing the pressure. The second outer peripheral portion has a predetermined cam radius larger than the first radius. The second outer peripheral portion contacts the supporting member when reducing the pressure.

Claim (Index 2):
The cleaning apparatus according to  claim 1 ,\n wherein the pressure reducing member is located integrally with the outer peripheral portion in one side of the outer peripheral portion, the pressure reducing member having a diameter identical to the diameter of the rotation roller, the pressure reducing member further including a cylinder portion on which the intermediate transfer belt is placed when the fitting hole is fitted to the rotation shaft, the cylinder portion has an abutting surface that abuts on an end portion in a longitudinal direction of the rotation roller when the fitting hole is fitted to the rotation shaft, and the outer peripheral portion has a contact surface that contacts an end surface in the width direction when the fitting hole is fitted to the rotation shaft.
