A developer container includes a container body and a movable wall. The container body includes a cylindrical internal space extending in a first direction and defined by an inner surface of the container body. The container body includes a developer discharge port. The movable wall includes an outer surface disposed in close contact with the inner surface of the container body, and a conveying surface defining a storage space configured to contain the developer. The movable wall moves to the developer discharge port in the first direction from one end side toward the other end side of the internal space, while conveying the developer in the storage space to the developer discharge port. The outer surface of the movable wall includes a discharge port sealing portion. When the movable wall is at the developer discharge port, the discharge port sealing portion covers the developer discharge port. |
