Claims

[Claims for Utility Model Registration] (1) A toner supply mechanism configured to supply toner from a toner cartridge to a toner supply member by engaging the toner cartridge with the toner supply member, wherein a cartridge body having a first opening that engages with the second opening, and for supplying the toner contained therein to the supply member through the respective first and second openings; , a lid member that opens and closes the first opening with a predetermined position of the first opening as the center of rotation; a space provided within the cartridge body that accommodates the lid member when the first opening is opened; a moving means for moving the lid member to a closed position so as to close the first opening when separated from the supply member; and a moving means provided on the supply member, with which the outer circumferential surface of the lid member abuts when the cartridge body is engaged. and a contact member protruding inward from the second opening so that when the cartridge main body engages with the supply member, the outer peripheral surface of the lid member is engaged with the contact member and stored in the space. A toner supply mechanism characterized in that: (2) The lid member has a movable wall extending from the lid member into the cartridge body, and when the first opening is opened, the movable wall forms a space in which the lid member is accommodated. The toner supply mechanism according to claim 1. (3) The toner supply mechanism according to any one of claims 1 and 2, wherein the moving means is provided within the cartridge main body at a position where it does not come into direct contact with the toner. (4) The contact member constitutes a part of the second opening, and when the cartridge main body engages with the supply member, the outer peripheral surface of the lid member contacts and the outer peripheral surface is retracted from the supply flow path. 4. The toner supply mechanism according to claim 1, wherein the toner supply mechanism is configured as follows.
