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 1):
A cleaning apparatus that removes a toner and a paper dust remaining on an intermediate transfer belt, the cleaning apparatus comprising:\n a pressing member; a pre-brush that contacts the intermediate transfer belt in a state of pressed to a side of the intermediate transfer belt with a predetermined pressure by the pressing member to charge the toner remaining on the intermediate transfer belt; a supporting member located between the pressing member and the pre-brush, the supporting member supporting the pre-brush movably in a separating direction to separate from the intermediate transfer belt; a removal roller that includes a first rotation shaft extending in a width direction of the intermediate transfer belt and removes the paper dust and the toner charged by the pre-brush on the intermediate transfer belt while contacting the intermediate transfer belt around the first rotation shaft; a recovery roller that includes a second rotation shaft in parallel to an axial direction of the first rotation shaft and recovers the toner and the paper dust on the removal roller from the removal roller by contacting the removal roller while rotating about the second rotation shaft; a cleaning blade that extends in parallel to an axial direction of the second rotation shaft, the cleaning blade contacting the recovery roller to scrape off the toner and the paper dust on the recovery roller; a sealing member that runs in parallel to the first and the second rotation shafts; a toner housing portion separated from the removal roller and the recovery roller by the sealing member, the toner housing portion housing the toner and the paper dust recovered by the recovery roller and scraped off by the cleaning blade; and a pressure reducing member that moves the pre-brush in the separating direction by pressing the supporting member in a direction opposite to pressing by the pressing member to reduce the pressure onto the pre-brush by the pressing member at every predetermined constant period, wherein the pressure reducing member includes:\n a fitting hole fitted to a rotation shaft of a rotation roller rotating at which the intermediate transfer belt is stretched; and\n an outer peripheral portion in a cam shape that has a diameter dimension larger than a diameter of the rotation roller, the outer peripheral portion being located around the fitting hole, and \n \n the outer peripheral portion includes a first outer peripheral portion and a second outer peripheral portion, the first outer peripheral portion having a predetermined first radius, the first outer peripheral portion not contacting the supporting member when not reducing the pressure, the second outer peripheral portion having a predetermined cam radius larger than the first radius, the second outer peripheral portion contacting the supporting member when reducing the pressure.
