PURPOSE:To simply and easily execute the loading/unloading of a toner cartridge by rotating a ring-shaped member directly or through a flange and disengaging a 1st pawl and a 2nd pawl which can be engaged with and disengaged from the engagement part of the flange. CONSTITUTION:At the time of replenishing toner, the toner cartridge is inserted into a toner cartridge mounting part 22 in a state where the 1st pawl 31 of the ring-shaped member 24 is engaged with the engagement part 30 of the flange 26 of a cylindrical body 23. When the flange 26 is rotated by a specified angle after completing the insertion, the 1st pawl 31 engages with a 2nd pawl 32 on a toner cartridge mounting part side. At the time of replacing the toner cartridge 21, the flange 26 is drawn this side and a ring-shaped member 24 is rotated a little in a state where a cylindrical body 23 is completely drawn out, so that the engagement of the 1st and the 2nd pawls 31 and 32 can be released and the toner cartridge 21 can be unloaded. Thus, the loading/unloading of the toner cartridge can be easily performed. |
