A cleaning sheet capable of cleaning and wiping the peripheral surface at least in line contact with the peripheral surface involved in printing, pressing means for keeping the cleaning sheet pressed against the peripheral surface of the rotating body, A cleaning sheet moving means for moving the cleaning sheet along the peripheral surface at a predetermined timing in a direction opposite to the rotation direction thereof, and the cleaning sheet moving means is disposed upstream of the pressing means in the moving direction of the moving means; A cleaning liquid supply means for supplying a cleaning liquid to the cleaning sheet. Since the cleaning sheet has sufficient water absorption and abrasion resistance as well as inclusive power and uniformity, the cleaning sheet is pressed against the peripheral surface of the rotating body. In cleaning and wiping, wiping can be performed evenly.In addition, cleaning can be performed efficiently with the cleaning solution sufficiently impregnated. Since it has an appropriate strength, it is possible to provide a wide range of designs of members related to the supply of the cleaning sheet. Further, since the cleaning sheet has a sufficient inclusive force for absorbing ink and dust, a life-prolonging effect can be obtained. Furthermore, since the filaments of polyester fibers or wood pulp fibers forming the nonwoven fabric adhere to the rotating body side during wiping and are retransferred onto the recording sheet due to the fact that they are not easily unraveled, the quality of printing may be impaired. There is no fear.
