を有することを特徴とする現像装置。[Scope of Claim for Utility Model Registration] Consisting of a developing device that is detachably attached to the main body of an image forming apparatus, and a toner cartridge that stores replenishment toner inside and has a toner discharge opening sealed with a sealing member. , by attaching the toner cartridge onto the supply port of the developer storage container of the developing device and pulling out the seal peeling member integrated with the sealing member, the opening of the toner cartridge and the developer are removed. In the developing device in which toner is replenished by communicating a supply port of a storage container, the developing device engages with the peeling member when the toner cartridge is attached to the developing device, and the peeling member engages with the peeling member. Replenishment frequency restriction unit consisting of a lever that rotates in conjunction with the action of pulling out a member, a stopper coaxially integrated with the lever, and a one-way spring that allows the lever and stopper to rotate in only one direction. is provided, the lever has one or more arms that protrude in the outer diameter direction and engage with the peeling member, and the stopper projects in the outer diameter direction and rotates by more than a predetermined angle. 1. A developing device comprising a stopper piece that is sometimes locked to prevent the peeling member from being pulled out.
