Abstract
A magnetic brush development apparatus includes a developer containing magnetic powder therein which is attracted to a non-magnetic support member by a magnet arranged therein. The developer is brought into contact with a latent electrostatic image bearing member which is located in a development section for developing the latent electrostatic image. The magnet has substantially one magnetic pole portion capable of producing a magnetic field having a plurality of peaks in the intensity of the magnetic field located in the development section.
