Abstract:
A toner cartridge includes a toner container that contains a toner, an auger screw, a toner discharge port, a shutter, an internal opening/closing valve and a stirring paddle. The internal opening/closing valve is provided as a member for closing the toner discharge port, in addition to the shutter. The shutter is fixed to a position at which the toner discharge port is always opened in a state where the toner cartridge is mounted in the image forming apparatus. The internal opening/closing valve is provided at a position facing the toner discharge port of a driving side end of a rotation shaft of the auger screw. The internal opening/closing valve is composed of a rectangular sheet member having flexibility, and closes the toner discharge port by blocking the entire toner discharge port.
