Patent abstract
A toner cartridge includes a chamber containing toner, a feeding portion configured to feed the toner toward an opening in the toner cartridge, and a pump configured to discharge the toner through the opening to outside of the toner cartridge, the pump being configured to move the toner by changing pressure inside of the toner cartridge relative to pressure outside of the toner cartridge. A rotatable coupling is configured to receive a rotational force from outside of the toner cartridge, the coupling being operatively connected to the feeding portion and the pump so as to transmit the rotational force to the feeding portion and the pump to thereby rotate the feeding portion and drive the pump.
