ABSTRACT:
A toner cartridge for a rotary developing device according to the current invention maximizes the storage capacity while it minimizes clogging or aggregation of stored toner. The toner cartridge is placed on an outer side surface of the rotary developing device and rotates around with the rotary developing device around the same axis of rotation. During the rotation, the stored toner is shaken and thrown against an internally projected dispersing portion in the cartridge for minimizing the aggregation of the toner. In addition, a vibration mechanism based upon the same rotational movement further minimizes the aggregation. The toner cartridges each containing a unique color such as cyan, magenta, yellow and black may be placed together to form a ring on the outer side surface. These toner cartridges are identical and maximize the storage capacity by substantially eliminating unused space between any adjacently placed cartridges.
