Abstract
A toner cartridge includes a screw configured to send stirred toner to an outlet through which the toner is discharged. The toner cartridge includes a partition between the screw and a toner stirrer. The toner stirrer at a default position is in contact with a top of the partition and covers the screw from above to define a closed space around the screw. The closed space is separate from a remaining space having the toner therein. The closed space is in communication with the remaining space when the toner stirrer rotates from the default position to be away from the toner transport screw, enabling the toner to move toward the toner transport screw.
