Abstract
A developing apparatus comprises a developing roll for carrying a nonmagentic toner thereon, and an elastic blade pressed against the outer circumferential surface of the developing roll to apply the toner thereto. The toner is 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 body to deposit the toner on a latent image on the photosensitive body. The developing roll has a surface which is opposite to the photosensitive body and the whole of which is roughened.
