PURPOSE:To easily recover a cartridge cover after it is used and to enable it to be utilized again by providing the cover on a cartridge and providing a toner housing member having a toner supply port inside and which is freely loaded or unloaded. CONSTITUTION:This toner cartridge 30 is provided with the cartridge cover 31 and a paper bag (toner housing member) 36 in which the toner is housed is fitted to a frame body 33. Then, the toner supply port of the paper bag 36 is formed at an aperture part on the lower surface of the frame body 33. In such a case, the supply port of the paper bag 36 is opened by taking up a take-up shaft 35. That means, when the cartridge 30 is exchanged, the paper bag 36 is removed from the inside of the cover 31 and the new paper bag 36 is fitted inside. Then, the aperture part is opened when the paper bag 36 is fitted to a developing device and the toner is supplied. Therefore, only the paper bag 36 is thrown out and the cover 31 can be utilized again. |
