Claims

[Scope of utility model registration request]

(1) A lid member provided at the developer supply port of the developer supply casing so as to open and close the replenishment developer cartridge receiving port by rotation around a horizontal axis, and a lid member provided within the developer supply port of the developer supply casing, The cylindrical outer circumferential surface is provided to rotate along the cylindrical inner circumferential surface of the lid member, and a part of the peripheral wall has a cartridge attachment/detachment opening in which a part of the peripheral wall is notched in the generatrix direction, and a replenishment developer cartridge is inserted through this attachment/detachment opening. a cylindrical cartridge holding member that holds the developer outlet so that the developer outlet opens into the male cartridge attachment/detachment port; and a cylindrical cartridge holding member that rotates the lid member and the cartridge holding member 2 relative to each other so that the lid member is in a closed state and the cartridge is installed. The prolapsed mouth is facing downward,
A developer replenishing device comprising: an interlocking mechanism that interlocks a lid member open state and a cartridge attachment/detachment opening upward state so as to correspond to each other.

(2) The replenishing developer cartridge has at least a substantially trapezoidal inner cross-sectional shape expanding from the bottom toward the developer discharge port. Device.
