ABSTRACT:
A toner supplying device which is capable of individually supplying toners of different colors. The toner supplying device can include a driving source; a plurality of toner receptacles in which different color toners are contained and respective toner discharging members are provided in order to discharge toners while being driven by power transmitted from the driving source; and a plurality of spring clutches to selectively transmit power from the driving source to the toner discharging members. The toner supplying device according to the present general inventive concept can be advantageously employed in toner-refill type color image forming apparatuses in view of the miniaturization of the apparatus and reduction in the manufacturing costs.
