Abstract
A cleaning device including a first blade contacting a surface of an image carrier and a second blade separate from the first blade to contact the surface of the image carrier at a position downstream from the first blade in a direction of rotation of the image carrier relative to a transfer position on the surface of the image carrier. A leading end of the second blade facing up is positioned upstream from a trailing end of the second blade relative to the direction of rotation of the image carrier. A first edge of the leading end of the second blade contacts the surface of the image carrier at a point on the surface of the image carrier below a second edge of the leading end of the second blade.
