Abstract
PURPOSE:To prevent flying off of developer in the sleeve revolving shaft direction before developing by disposing a developer defining member and a scooping up member to the end part of the sleeve, in a magnetic brush developing device. CONSTITUTION:A sealing material 23 composed of felt, sponge or the like is provided on approximately the entire circumference of the recess 18a of a sleeve 18 which conveys the developer while holding the same on its outside circumferential surface by the magnetic force of a rotating magnet 20. A sccoping-up member 24 composed of a metal piece, elastic blade or the like is disposed between said sealing member 23 and the shoulder part of the sleeve 18 in such a manner that it intermeshes therewith. This member is then fixed to the stationary blade 20 of a hopper 15 by means of screws 25. Then, if the developer being conveyed by the sleeve 18 moves in the rotating shaft direction of the sleeve 18 and tries to fly off, it is guided to the scooping-up member 24 side by the sealing member 23 and is scooped up into the hopper 15.
