ABSTRACT:
A developer cartridge of an image forming apparatus includes a cartridge frame having a developer chamber holding a developer therein, and a developer discharging port, a developer conveying unit rotatably installed on the cartridge frame to agitate and move the developer towards the developer discharging port, and an elastic damper to change the size of a developer discharge space defined by the vicinity to the developer discharging port according to a developer delivery pressure of the developer conveying unit. The damper contracts to increase a size of the developer discharge space and reduce the developer delivery pressure, when the developer delivery pressure increases above a normal pressure in the developer chamber.
