Claims

[Scope of utility model registration request]

In a developer replenishment device in which a hopper for replenishing replenishing developer is provided in the developing device and developer is replenished through the hopper, a replenishing developer cartridge with an open mouth is removably attached and closely spaced. The cylindrical cartridge holder to be mounted is supported so as to be rotatable around a horizontal axis with respect to the hopper, and the inside of the cartridge holder is rotatable around the horizontal axis and is normally attached to the hopper side of the cartridge holder. The hopper is provided with a shielding plate that is biased to close the opening, and when the cartridge holder is rotated to the set position on the hopper, the shielding plate is pressed to move the shielding plate from the closed state. A developer replenishing device characterized by being provided with a protrusion for shifting to an open state.
