Abstract

Apparatus for developing a latent image in electrophotographic or electrostatic processes includes a magnet assembly for forming a magnetic developing brush which can be supplied with and carry a developer mix in a development region. The magnet assembly includes a plurality of curved, sector shaped magnets for carrying the mix to and from the development region and a rectangular cross-sectional magnet of greater magnetic force at the development region.
