Abstract: A developer container includes a container body, a shaft, a movable wall, and a stirring member. The container body is formed with a developer discharge port. The developer discharge port lies at a position higher than a lowest part of the container body by a predetermined amount. The movable wall includes an outer surface slidably in close contact with an inner surface of the container body, and a conveying surface defining a storage space for the developer in cooperation with the inner surface of the container body. The movable wall moves along the shaft in the internal space while conveying the developer in the storage space to the developer discharge port. The stirring member is rotated around an axis of the shaft in a specified rotational direction to stir the developer, the specified rotational direction proceeding from the lowest part of the container body to the developer discharge port.

Abstract: A toner container includes a container body, a tubular body, and a screw feeder. The tubular body forms a toner conveyance path communicating with an inside of the container body. The screw feeder feeds toner in the container body to the toner conveyance path by being rotationally driven inside the container body. The screw feeder pushes toner that has arrived inside the toner conveyance path further along the toner conveyance path by feeding pressure of succeeding toner.

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.

Abstract: An image forming apparatus includes a housing in which a developing device is disposed, a cover member attached to the housing, a developer storage container to be detachably attached to the developing device, and a sensor unit. The developer storage container includes a container body having a storage space for storing a developer and a developer discharge port, and a moving wall configured to move in the container body. The sensor unit is arranged at a detection position where a detection sensor faces a specific area located above the developer discharge port on an outer peripheral surface of the container body when the cover member is in a closing posture, and arranged at a detection disable position where the detection sensor is distant from the specified area when the cover member is in an opening posture.

Abstract: Provided are a developer storage container in which a large change of a developer distributed state due to a backward movement of a moving wall is restrained and an image forming apparatus provided with the developer storage container. A toner container includes a container body, a moving wall and a shaft. The moving wall includes a first wall portion and a second wall portion. When the shaft is rotated in a first rotating direction, the second wall portion presses the first wall portion, whereby the second wall portion moves in a first direction integrally with the first wall portion. When the shaft is rotated in a second rotating direction, the second wall portion relatively moves to an upstream side in the first direction with respect to the first wall portion.
