Magnetic brush development apparatus

摘要

Magnetic brush development apparatus for use in reproduction apparatus in which a support carrying a developable latent image is moved through a development zone which is transversely inclined at a predetermined angle to the horizontal. The development apparatus includes a stationary non-magnetic inclined applicator with a segment located adjacent to the development zone. The applicator is supplied with magnetic developer which is distributed over the surface of the applicator through the influence of gravity and of a magnet assembly rotatably mounted within the applicator. A reservoir associated with the applicator accumulates developer moved about the periphery of the applicator and levels it to produce a uniformly thick layer in the development zone. A transport assembly is positioned at the inlet to the reservoir to transport excess developer from the reservoir back up the applicator against the influence of gravity to deposit developer in the reservoir in areas which are deficient in developer and to remove excess developer from the applicator at the upper end thereof when the reservoir is full.
