ABSTRACT:
A toner feeding assembly for feeding a developer mixture of a toner and carrier particles to an intermediate carrier which has been electrostatically charged, the feeder mechanism employing magnetic brushes of the rotating cylinder type, at least one of the brushes being adjacent the intermediate carrier. An excess toner deflecting guide member is positioned adjacent the magnetic brush-intermediate carrier nip having one long side edge projecting towards the nip and an opposite long side edge positioned away from the nip and below the one edge. The guide is effective to direct a film of developer mixture away from the nip area and back to a developer mixture reservoir.
