ABSTRACT:
A toner cartridge is extractably set in a storing recess of an image forming apparatus main body, and toner is supplemented to a specified part of the image forming apparatus main body. While the toner cartridge is brand-new, an inner seal member peelably adhered to the lower surface of the toner cartridge main body seals the toner dropping opening at the lower surface. After setting the toner cartridge in the storing recess, by peeling off and taking up the inner seal member by the take-up shaft, the toner dropping opening is unsealed. An outer seal member provided slidably along the lower surface of the toner cartridge main body opens or closes the toner dropping opening beneath the inner seal member. When the toner cartridge is drawn out from the storing recess, an outer seal member operating member becomes engaged with an engaging part of the image forming apparatus main body, thereby automatically closing the outer seal member.
