ートリツジ。[Scope of Claim for Utility Model Registration] 1. A cartridge body having a downwardly opening opening, a closing member rotatably attached to the cartridge body and capable of freely opening and closing the opening of the cartridge body, and a cartridge provided in the closing member. When the cartridge main body is installed in a predetermined position of the toner replenishing device, the closing member rotates relatively by engaging with the engaged portion formed on the inner surface of the case of the toner replenishing device. A toner cartridge having an engaging portion capable of opening an opening. 2. The cartridge main body is formed into a substantially cylindrical shape, the closing member is installed in the cartridge main body so as to be rotatable in the circumferential direction, and the engaging portion provided on the outer surface of the closing member engages the elongated hole formed in the cartridge main body. The engaged portion extends through and protrudes to the outside, and includes a linear portion substantially parallel to the insertion direction of the cartridge body provided on the outside of the case and an insertion direction of the cartridge body provided on the inside of the case. The toner cartridge according to claim 1, which has a spiral portion that is inclined with respect to the direction of the toner cartridge. 3 At the side edge of the closing member opposite to the rotational direction, a cartridge main body is inserted into the case and the engaging portion of the closing member engages with the spiral portion of the case, so that the closing member rotates relative to the side edge thereof. The toner cartridge according to claim 2, wherein a closing edge is formed that can close an opening of the cartridge main body outside the toner replenishing device when the toner cartridge is loaded.
