ABSTRACT:
A cleaning device for a monochromatic copying machine for processing residue toner removed by a blade assembly from a photoreceptor, which machine is of a type capable of accommodating selectively a plurality of developer boxes containing respective masses of toner of different colors, which device comprises a toner recovery duct extending between a cleaning box, adapted to accommodate therein residue toner removed from the photoreceptor, and a developer box, for feeding the residue toner accommodated within the cleaning box towards the developer box. One of the developer boxes for use with the mass of black-colored toner has a single chamber defined therein and communicated with the toner recovery duct when such a developer box is set in position within the copying machine, whereas each of the remaining developer boxes for use with the masses of toner of respective colors other than black has working and collecting chambers defined therein, separated by a partition wall from each other. The collecting chamber in each of the remaining developer boxes is communicated with the toner recovery duct when any one of the developer boxes is set in position within the copying machine.
