ABSTRACT:
A developer filling apparatus includes a developer supply container for containing a developer and compressed air, the developer supply container includes a developer discharge mechanism, the developer discharge mechanism including a developer outlet opening for discharging the developer and compressed air, and a valve structure disposed at the developer outlet opening for normally closing the developer outlet opening and for opening the developer outlet opening upon application of an external force. Accordingly, because a developer cartridge can be easily filled with a developer using the force of compressed air in a developer filling operation, the developer filling operation can be performed more easily in comparison to a conventional manual one utilizing a developer measuring container. In addition, the developer is prevented from being blown around during the developer filling operation, thereby improving working conditions and avoiding environmental pollution.
