PROBLEM TO BE SOLVED: To provide a toner cartridge capable of opening/closing a toner discharging port securely and easily even in the case only an amount of toner equal to an amount of toner consumed and reduced in the device as of a copying machine is supplied sequentially from a toner cartridge, thereby preventing a change in the quality of the toner in a toner container for a long time. SOLUTION: The toner container 204 is equipped with a contracting part which contracts according to an amount of the decrease of toner in the toner container, and by injecting toner from a discharging part 201, the inside of the toner container 204 is filled with the toner from the state of the contraction of the contracting part of the toner container. The valve body 206 of the toner discharging part 201 has a main fitting part 209 for closing the discharging port 208 by fitting with the discharging port 208, and also has a connection part 213 which is connected to the valve-body operation part 211 of the device as of the copying machine. When the valve-body operation part 211 of the device moves downward, the connection part 213 moves together with the valve- body operation part 211 while being kept connected to the valve-body operation part 211, the main fitting part 209 and discharging port 208 are fitted with each other, and thus the discharging port is securely closed. |
