Abstract
The toner cartridge of the present invention has an elongated cylindrical container containing toner and is set at a predetermined position such that the lengthwise axis of the container extends in the substantially horizontal direction. A supply port for dropping and supplying the toner in the container in the gravity direction toward the apparatus body. An auger extended immediately above the supply port in the substantially horizontal direction is provided in the container. The auger rotates thereby feeding the toner from inside the container toward the supply port along the rotary shaft. A plate-like regulation member for restricting drop of the toner in the container toward the supply port due to its dead weight is attached to a position opposed to the supply port above the auger.
