Title: Magnetic brush developing device
Inventor: SOUMA SHINOBU
IPC: G03G15/01
Filed: 1984-12-21
Abstract: PURPOSE:To control the thickness of a developer layer smoothly and accurately by arranging magnetic poles of a magnet body nearby a doctor blade and at its downstream side and providing a gate member which has a face opposite to the magnetic poles and consists of the magnet body or magnet moving toward and away from the surface of a developing sleeve. CONSTITUTION:When the developing sleeve 3 rotates while the gate member 11 leaves the developing sleeve 3 and a latent image formation surface reaches a development area, development is carried out by the developer layer whose thickness is controlled by the doctor blade 10. The gate member 11 is moved to nearby the developing sleeve 3 when or slightly before the latent image formation surface of an image carrier 1 finishes passing through the development area. When the gate member 111 comes close, lines of intense magnetic force between a magnetic pole N2 and the gate member 11 restrains the developer layer which is to move through the rotation of the developing sleeve 3 to stop it movement. Consequently, the wear of the image carrier and the staining of a recording paper background part, at the inside of a copying machine, etc., are prevented and the consumption of a developer is reduced, thereby reducing the load on a cleaning device.
