Abstract
A magnetic brush development apparatus for developing latent electrostatic images formed on a flexible latent electrostatic image bearing member by a magnetic brush employing powder developer containing a magnetic material. The latent electrostatic image bearing member is positioned in contact with or in proximity to the magnetic brush formed on a sleeve for development. In a portion where the sleeve and the latent electrostatic image bearing member are positioned in proximity to each other, there are formed two spaces whose cross sections are wedge-shaped and development of the latent image is performed in the space on the upstream side with respect to the transport direction of the latent image bearing member and the unnecessary toner deposited on the latent image bearing member is cleaned in the other space on the downstream side.
