Abstract
A cleaning blade includes an elastic member that includes a front edge surface extending in the longitudinal direction of the elastic member and the thickness direction orthogonal to the longitudinal direction and a bottom surface extending in the depth direction orthogonal to the longitudinal direction and the thickness direction, the bottom surface sharing a front edge ridge part with the front edge surface and facing a cleaning target, and a coating layer coating the front edge surface, the front edge ridge part, and the bottom surface, wherein the front edge ridge part coated with the coating layer is in contact with a surface of the cleaning target, and the coating layer has an average thickness that increases with an increase in a distance from the front edge ridge part in the thickness direction on the front edge surface.
