ABSTRACT:
A toner cartridge is a developer storage container for storing toner (developer) in a hollow cylindrical section that is driven to rotate on its axis so that the stored toner is discharged from an outlet. The cylindrical section has an inner circumferential surface provided with a plurality of liner protruding portions that extend in a direction tilted with respect to a rotation direction of the cylindrical section. Moreover, the toner cartridge includes a stirring member capable of moving in the cylindrical section so as to collide with the protruding portions. This makes it possible to stably supply a developer and to realize an inexpensive developer storage container whose size can be reduced.
