Abstract
PURPOSE: To obtain a good stable magnetic brush development device wherein at the bottom of a hopper-like developer reservoir is provided with a non-magnetic cylindrical drum with a built-in permanent magnet, and the cylindrical drum is so constructed that a part of the drum is rotatable as if it would encroach into the reservoir, and a toner taking out opening is made smaller than the retrieval opening.
