Abstract:
A developer storage container includes a container body, a shaft, a moving wall and a pressing member. The container body has an inner peripheral surface defining a tubular internal space extending along a first direction. The shaft is arranged to extend in the first direction in the internal space and rotatably supported. The moving wall is movable in the first direction in the internal space while conveying the developer in the internal space toward a developer discharge port. The pressing member moves integrally with the moving wall by pressing the moving wall when the shaft is rotated in a first rotating direction and relatively moves to an upstream side with respect to the moving wall according to the engagement of a first engaging portion and a second engaging portion when the shaft is rotated in a second rotating direction opposite to the first rotating direction.

Claim (Index 1):
A developer storage container, comprising:\n a container body having an inner peripheral surface defining a tubular internal space extending along a first direction, the container body being formed with a developer discharge port open to communicate with the internal space and allowing a developer to be discharged; a shaft arranged to extend in the first direction in the internal space and rotatably supported in the container body, the shaft including a first engaging portion spirally formed along the first direction on an outer peripheral surface; a moving wall including a first bearing portion, the shaft being inserted through the first bearing portion, an outer peripheral surface arranged in contact with the inner peripheral surface of the container body and a conveying surface defining a storage space for storing the developer together with the inner peripheral surface of the container body, the moving wall being movable in the first direction along the shaft in the internal space while conveying the developer in the internal space toward the developer discharge port; and a pressing member arranged upstream of the moving wall in the first direction, the pressing member including a second bearing portion, the shaft being inserted through the second bearing portion, a second engaging portion arranged on an inner peripheral surface of the second bearing portion and engageable with the first engaging portion, and a pressing portion configured to press the moving wall in the first direction, the pressing member being configured to move in the first direction integrally with the moving wall by the pressing portion pressing the moving wall according to the engagement of the first engaging portion and the second engaging portion when the shaft is rotated in a first rotating direction and relatively move to an upstream side in the first direction with respect to the moving wall according to the engagement of the first engaging portion and the second engaging portion when the shaft is rotated in a second rotating direction opposite to the first rotating direction.
