Abstract
A cleaning apparatus cleans an image carrier including an elastic layer after a toner image formed on the image carrier is transferred to a transfer material. The cleaning apparatus includes a rigid blade that cleans a residue attached on a surface of the image carrier by contacting the image carrier from which the toner image has been transferred to the transfer material. The rigid blade includes a metal base and a coating layer formed on a surface of the metal base. The coating layer is disposed at least at an edge portion of the base that contacts the image carrier. An upstream part of the edge portion has a rounded shape with a radius of curvature that is less than an average radius of toner particles.
