ABSTRACT:
A developing apparatus is provided with a developing roller for carrying a toner thereon and an elastic blade pressed against the surface of the developing roller to apply the toner thereto. The toner is thus applied to the surface of the developing roller by the elastic blade to form a thin layer of the toner on the surface of the developing roller. The thin layer is opposed to a photosensitive drum at a predetermined space to deposit the toner on an electrostatic latent image on the photosensitive drum. Magnets and magnetic particles are provided to prevent the toner from leaking out.
