ABSTRACT:
A magnetic brush developing device for a xerographic copying machine is constructed to prevent toner from being leaked out of the developer housing. A magnetic brush roll is provided opposite to a photosensitive member, and at least one air current blade is provided along the lower outer periphery of the surface of the magnetic brush roll. One end of the air current blade is closely adjacent the surface of the photosensitive member, and the other end of the air current blade projects back toward the interior of the developer housing. An air circulating path is defined between the air current blade and the lower outer wall of the developer housing. This air circulating path is effective to conduct entrained air carrying excess toner back into the developer housing.
