The shutter includes a first engagement surface positioned to receive a first engagement member of the toner cartridge to begin to open the shutter as the toner cartridge is inserted in the image forming device. The shutter also includes a second engagement surface positioned to receive a second engagement member of the toner cartridge to move the shutter a remaining distance to the open position.
