Abstract (en)
In a magnetic brush development apparatus in which a developer containing magnetic powder therein is attracted to a non-magnetic support member (10) having a magnet (11) therein, and said developer attracted to said non-magnetic support member (10) is brought into contact with a latent electrostatic image bearing member in a development section for developing said latent electrostatic image, the improvement wherein said magnet (11) has substantially one magnetic pole portion capable of producing a magnetic field having a plurality of peaks (14) in the intensity of said magnetic field in said development section.
