Abstract
A cleaning device to remove untransferred toner from a surface of an image carrier rotatable in a predetermined direction. The cleaning device includes a lubricant supply roller contacting the surface of the image carrier to supply a lubricant carried thereon to the surface of the image carrier, a first blade provided upstream from the lubricant supply roller in the direction of rotation of the image carrier, and a second blade provided downstream from the lubricant supply roller. The first blade contacts the surface of the image carrier to level the untransferred toner attaching to the surface of the image carrier to a thin layer. The second blade contacts the surface of the image carrier to level the lubricant supplied to the surface of the image carrier by the lubricant supply roller to a thin layer and to remove the untransferred toner from the surface of the image carrier.
