TONER SUPPLY APPARATUS AND TONER CARTRIDGE

摘要

The present invention relates to completely closing an outlet of a toner cartridge with a shutter (650). The shutter (650) for closing the outlet (620) has a shutter-side joining part (653). A toner cartridge retention member (700) has a retention-side joining part (711) which is joined with the shutter-side joining part (653) and closes the outlet (620) by making the shutter (650) slide according to movement of a toner containing part (610); a retention joining part (713) which prevents the toner cartridge (600) from moving in the direction of disassembling the retention-side joining part (711); and a retention-sided guide unit (714) which guides the toner cartridge (600) in the direction of disassembling the shutter-side joining part (653) after the outlet (620) is closed. The cartridge part (600) has a cartridge-side guide part (611) which prevents the shutter (650) from moving in the direction of disassembling the shutter-side joining part (653) until the outlet (620) is closed.
