PURPOSE:To prevent toner from scattering around a developing machine and to allow an operator to perform operation easily without staining the hands, by attaching a bag to the cartridge insertion opening of the developing machine when an empty cartridge is drawn out of the developing machine after toner is supplemented, and drawing the cartridge out while putting it in the bag. CONSTITUTION:The front end of the bag 13 is passed through a ring 12 and fixed with a cord 14, and the ring 12 is fitted around a pipe 15 until the front end of the ring 12 abuts on the end surface of a pipe holding metallic fitting 16. Then, the bottom part of the bag 13 is pressed in with a hand as shown by an arrow to cover the pipe 15, forming the double bag. When the cartridge is detached, the opening part 6 of the cartridge 3 is set upward and the ring 12 including the double folded bag 13 is attached to a flange 11; and the cartridge is drawn out from outside the bag 13 to put the cartridge 3 in the bag 13. |
