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. |

1. A developer container, comprising:
a container body including an inner surface defining a cylindrical internal space extending in a first direction, and a first wall disposed at one end of the container body in the first direction and defining one end surface of the internal space, the container body being formed with a developer discharge port opening in a circumferential portion of the container body, the developer discharge port being disposed at a position higher than a lowest part of the container body by a predetermined amount and communicating with the internal space, the developer discharge port being configured to discharge developer therethrough; a second wall disposed at the other end of the container body that is opposite to the first wall in the first direction and defining the other end surface of the internal space; a shaft disposed in the internal space and above the discharge port, extending in the first direction, and supported on the first wall and the second wall; a movable wall including an outer surface slidably in close contact with the 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 being movable along the shaft in the internal space while conveying the developer in the storage space to the developer discharge port; and a stirring member facing the developer discharge port in a direction intersecting the first direction and rotatable around an axis of the shaft in a specified rotational direction to stir the developer in the storage space, the specified rotational direction proceeding from the lowest part of the container body to the developer discharge port. |
