Claims

[Claims for Utility Model Registration] (1) In a toner cartridge that is attached to a developing device and replenishes toner from a replenishment opening of the developing device, the replenishment opening of the developing device includes an elastic lid having a number of notches. A member is arranged to close it,
A slide plate is disposed on the upper surface of the elastic lid member so as to be slidable along its length, and a rack gear is further disposed parallel to one side edge in the length direction of the elastic lid member, and the slide plate , having a replenishment port, a lid that rotates downward to open the replenishment port, a spring that biases the lid to a normally closed position, and a spring that holds the slide plate at the replenishment start position, The toner cartridge includes a cylindrical toner storage cylinder, a partition blade rotatably supported within the toner storage cylinder around a central axis of the storage cylinder, and a partition blade that extends radially from the center of the partition blade in an outer radial direction. a fan-shaped toner storage chamber defined between a plurality of partition plates and the inner wall of the storage cylinder; an opening formed in the bottom surface of the toner storage chamber and having a shape capable of communicating with one toner storage chamber; A pin that protrudes downward from the periphery of the opening to open the lid against the spring, and a drive gear that is exposed through a window on the bottom of the cartridge and meshes with the rack gear to rotationally drive the partition blade. Characteristic toner cartridge. (2) In the toner cartridge according to claim (1), two adjacent specific storage chambers of the toner storage chambers are empty storage chambers that do not store toner, and one of the toner storage chambers is in an initial state at the time of starting replenishment. A toner cartridge, characterized in that the toner cartridge faces the opening of the toner storage cylinder.
