PROBLEM TO BE SOLVED: To provide a toner cartridge capable of preventing a toner from scattering from an exhaust port as much as possible.SOLUTION: A toner cartridge 5 includes a toner cartridge body 6 having therein a toner storage chamber 6a and an exhaust port 9 discharging a toner 8 on a trunk part of the toner cartridge body 6, and a shutter member 7 provided movably on the toner cartridge body 6 to open and close the exhaust port 9. The shutter member 7 has an inner peripheral surface 7a' facing an outer peripheral surface 6b' of the toner cartridge body 6; and the exhaust port 9 is provided with a toner guide port bag 10 that is folded to be overlapped between the outer peripheral surface 6b' and the inner peripheral surface 7a' to seal the exhaust port 9 when the shutter member 7 is moved relatively to the toner cartridge body 6 in a direction to close the exhaust port 9, and is drooped to discharge, while guiding, the toner 8 when the shutter member 7 is moved relatively in a direction to open the exhaust port 9 so that the exhaust port 9 is directed downward. |
