Abstract
PURPOSE: To uniformalize a soft brush layer and development, by providing a flat plate for leveling a magnetic brush between a developing surface and a position for feeding developer and specifying the plate in relative position and inclination angle.
CONSTITUTION: Magnetic brush-leveling flat plate 3 is arranged in the position apart from development face B1 of magnetic brush developing roller 1 by 90° or more in the direction reverse to rotation between face B1 and developer supplying position E, and the distance b between the inside end of plate 3 and a magnetic brush rotation center is kept a≥b, where a is the distance between the rotation center and face B1, and the inclination angle of plate 3 is made 90° or more with face B1. As a result, the magnetic brush rotating toward face B1 from position E is resisted by plate 3, tends to accumulate below plate 3, raises developer density, comes out of the opening below the end of plate 3 in uniform thickness and high density, actively rises as a soft brush, and forms a uniform layer, thus permitting even uniform development to be made.
