A developer container (30) includes a container body (31), a movable wall (34), and a stirring member (32). The container body (31) includes an inner surface (31 K) defining a cylindrical internal space (31H) extending in a longitudinal direction, and a developer discharge port (319). The developer discharge port (319) is formed in a lower part of the inner surface (31K). The movable wall (34) includes an outer surface (34K) disposed slidably in close contact with the inner surface (31K) of the container body (31), and a conveying surface (340S). The conveying surface (340S) defines a storage space (31 S) for developer. The movable wall (34) moves while conveying the developer in the storage space (31S) to the developer discharge port (319). The stirring member (32) stirs developer in the storage space (31S). |
