Abstract (en)

A toner cartridge is provided which may surely and easily open and close a toner outlet when only the amount of toner corresponding to the amount used up in the device such as copying machines is supplied from the toner cartridge in sequence as needed, and which may preserve the toner without deterioration for a long period of time. By introducing toner through a toner discharge member 201 of the toner container 204, the toner container 204 is filled with the toner. A valve body 206 of the toner discharge member 201 includes a main fitting portion 209 of closing the outlet 208 by fitting in the outlet 208, and a connecting portion 213 adapted to be connected with a valve body operating member 211 of the device such as copiers. If the valve body operating member 211 of the device descends, the connecting portion 213 moves together with the valve body operating member 211 by contact with the latter to achieve a fitting connection between the main fitting portion and the outlet 208, thereby to ensure a closing to the outlet. <IMAGE>
