Abstract
A developer container includes a container body, a movable wall, and a stirring member. The container body is formed with a developer discharge port opening in a circumferential portion of the container body and communicating with an internal space for allowing discharge of developer therethrough. 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 being movable in the first direction in the internal space while conveying the developer in the storage space to the developer discharge port. The stirring member faces the developer discharge port in a direction intersecting the first direction and is rotatable to stir the developer in the storage space. The movement of the movable wall and the rotation of the stirring member are controlled independently of each other.
