Abstract
A developing apparatus is provided with a developing roller for carrying a toner thereon in a housing. An elastic blade is pressed against the surface of the developing roller in one direction to apply the toner, so that the toner is applied to the surface of the developing roller by the elastic blade to form a toner layer on the surface of the developing roller. The toner layer is opposed to a photosensitive drum at a predetermined space to deposit the toner on a latent image on the photosensitive drum. The elastic blade comprises a fixed plate and a contact plate which are fixed to each other at one end thereof. The other end of the fixed plate is fixed to the housing. A central portion of the contact plate is pressed against the surface of the developing roller.
