ABSTRACT:
A toner cartridge mountable to a cartridge mount of a main assembly of an image forming apparatus comprising an electrostatic latent image bearing member, and a toner container for containing toner for developing an electrostatic latent image on the image bearing member, wherein the cartridge is disposable in a mounting position, where the toner cartridge can be mounted on or dismounted from the cartridge mount, and a toner supply position, where toner can be supplied into the container from the toner cartridge. When toner is to be supplied into the container, the toner cartridge is rotated in a predetermined direction from the mounting position to the supply position, and when the toner cartridge is to be dismounted from the cartridge mount, the toner cartridge is rotated in the opposite direction. The toner cartridge includes a container body for containing the toner, and a toner discharge opening is provided in the container body for discharging toner from the container body. A shutter opens and shuts the discharge opening. A shutter support supports the shutter for movement between a closed position and an open position. A projection located at a corner portion of the support is engageable with an engaging portion of the cartridge mount, wherein when the toner cartridge is at the toner supply position, the projection is engaged with the engaging portion to prevent removal of the toner cartridge from the cartridge mount.
