Abstract

PURPOSE:To surely recover toner from a cleaning device, by forming spikes of developing agent sufficiently on an endless belt through reversing the polarity of a magnet used for a toner recovery device from that of main magnet at a developer. CONSTITUTION:A device which automatically recovers the toner caught at a cleaning device to a developer, is coaxially located adjacent to a photo conductive drum so that a part of the circumference can be opposed to the magnetic brush device of the developer 4, and consists of a non-magnetic substance drum 17 fixing magnets 19 inside, endless belt 21 made of non-magnetic substance belted to the drum and a part of which is introduced to a developer apart from the drum, and means inducing toner caught with the cleaning device to the spikes B of the developing agent formed on the surface of the endless belt 21 with magnetic force of the magnet 19. The polarity of the magnet 19 is reversed from the polarity of a main magnet 11a at the developer side.
