Claims

[Scope of Claim for Utility Model Registration] In an image recording device that forms an electrostatic latent image on a photoreceptor, develops it with a developing device, and transfers the developed image onto recording paper, toner is applied to a fixedly arranged developing device. A replaceable toner cartridge having a supply port for replenishment is integrally incorporated therein, and a replacement supply kit is removably supported by a support member provided on the main body of the recording apparatus, and the supply kit includes the above-mentioned toner cartridge. a shutter that is movable to open and close with respect to the supply port of the toner cartridge; a locking member that locks the shutter in a closed position; and a release means that is provided on the support member and that unlocks and moves the locking member at a predetermined mounting position. , an opening/closing moving member for opening the shutter, and when the supply kit is attached to the support member, the releasing means releases the locking of the shutter by the locking member, and the opening/closing moving member automatically locks the shutter. When the shutter is moved to open and the supply kit is separated from the support member, the shutter is moved to close by the opening/closing member in accordance with the movement of the supply kit, and the locking member engages and locks the shutter in the closed position. A supply kit for an image recording device characterized by:
