Abstract
A developer container includes a container body, a movable wall, a shaft, 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. 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. The movable wall conveys the developer to the developer discharge port from a predetermined initial position owing to repeated movements of the movable wall in the first direction and a second direction. When the shaft is rotated in a first rotational direction, the movable wall moves in the first direction, and when the shaft is rotated in a second rotational direction opposite to the first rotational direction, the movable wall moves in the second direction.
