ABSTRACT:
The development apparatus develops a latent image formed on a photo-conductor using a developer composed of a toner and a magnetic currier particle. A development sleeve carries the developer on an outer surface thereof so as to transfer the developer to the photo-conductor. A developer application mechanism applies the developer to the outer surface of the development sleeve. A plurality of magnets are provided inside the development sleeve so as to generate a magnetic field so that a magnetic brush is formed by the developer. The magnetic brush is brought into contact with said latent image carrier in a development area where the developer carrier is contiguous to the latent image carrier and the magnetic field between the latent image carrier and the developer separates the toner from the magnetic carrier of the magnetic brush. The wherein the magnetic brush is separated from the latent image carrier outside the development area.
