Abstract
A developer cartridge is provided with a cartridge main body with a supply port for supplying developer to an apparatus main body of an image forming apparatus, a shutter member displaceable between an opening position for opening the supply port and a closing position for closing the supply port, an operation lever arranged to face the opening cover and adapted to displace the shutter member between the opening position and the closing position, and a biasing member for biasing the operation lever toward the closing posture. The operation lever is displaceable between an opening posture corresponding to the opening position and a closing posture corresponding to the closing position. The operation lever is displaced from the closing posture to the opening posture against a biasing force of the biasing member due to interference with a part of the opening cover when the opening cover is closed.
