摘要： A cleaning unit (8) includes a first blade (8a) and a second blade (8b). The first blade (8a) is in contact with an image carrier (1) or a paper carrier and removes adhered substances remained on surface of these. The second blade (8b) has an abrasive layer (8b-1) that is formed by including abrasive particles in an elastic material and is disposed in the downstream side of the first blade (8a). The second blade (8b) is allowed to be in contact with the image carrier (1) or the paper carrier. Volume occupancy of abrasive particles in an area of contact of the second blade (8b) with either the image carrier (1) or the paper carrier is not less than 50 percent and not more than 90 percent.
