Abstract
A combined cleaner and toner magazine (CTM) applicable to an image forming apparatus and implemented as a single unit made up of a device for supplying a toner to a developing unit and a cleaning device for removing and storing part of the toner which remains on a photoconductive element after image transfer. The CTM has an electromagnetic shutter or a permanent magnet for preventing the toner left on the photoconductive element without being collected by the cleaning device from being scattered around in the apparatus. When a toner reservoir included in the toner supply device is emptied and, at the same time, a waste toner tank in the cleaning device is filled up, a supplementary toner is filled in the toner reservoir via a predetermined opening and the waste toner is discharged from the waste toner tank via another predetermined opening.
