ABSTRACT:
A magnetic brush developing apparatus as disclosed having magnetic rollers with end sleeves formed of an insulating material. A trimming bar is provided having a concave portion below a leading edge thereof to facilitate the return to the sump zone of excess developing material and having a flat surface forming a converging passageway with a said roller whereby to compress developing material transported on said roller. Magnets disposed within the rollers are mounted on channel members in a manner to direct the magnetic forces about each brush to ensure blanket coverage and a downstream configuration to direct developing material over a baffle associated with a cross-mixing baffle assembly. A screen is provided within the housing of the assembly to collect foreign objects. A mixing and transport device is positioned within the sump zone and is comprised of a plurality of spaced-apart augurs disposed on a shaft and a plurality of radially-extending bars affixed to the ends of the augurs.
