Abstract
A developing apparatus is constructed so that a first rugged surface portion is formed on that portion of the surface of an elastic blade which faces and is pressed against a developing roller, thereby reducing the conveying force to carry the developing agent in contact with the first rugged surface portion under the pressure of the elastic blade. In this way, the layer of the developing agent flowing to the contact point between the developing roller and the elastic blade is gradually thinned to form a uniformly thin layer of developing agent on the surface of the developing roller.
