Claims

[Claims for Utility Model Registration] A cartridge having a closing surface that closes the discharge port of a cartridge containing developer, and an opening that opens the discharge port by rotating this closing surface,
With the discharge port closed by the closing surface,
a discharge port opening/closing member rotatably supported with respect to the side wall of the cartridge; and a rectangular portion formed coaxially with the discharge port opening/closing member and extending outward through the side wall of the cartridge. a rotating knob formed on a side wall of a hopper of a developing device into which the cartridge is mounted with the discharge port facing downward; a guide groove formed in a width to which the short side of the rectangular portion is fitted to guide the rectangular portion of the rotation knob along the longitudinal direction of the rectangular portion; and a cartridge installed in the hopper;
A developer replenishment mechanism comprising: a guide hole formed at an end of the guide groove of the hopper and having a size that allows rotation of the rectangular portion within the guide groove.
