ABSTRACT:
A developing apparatus is provided with a developing roll for carrying a toner thereon and an elastic blade pressed against the surface of the developing roll to apply the toner thereto. The toner is thus applied to the surface of the developing roll by the elastic blade to form a thin layer of the toner on the surface of the developing roll. The thin layer is opposed to a photosensitive drum at a predetermined space to deposit the toner on an electrostatic latent image in the photosensitive drum. A regulation member is attached to the housing so as to positioned between the housing and the elastic blade. The regulation member has an outlet port of a first width at a central portion thereof. The elastic blade is pressed against the developing roll with a second width greater than the first width.
