    a developer discharging body in fluid communication with the developer accommodating body, the developer discharging body having a discharge opening, the discharge opening being configured to form at least a part of a discharge passageway through which developer may be discharged to outside of the developer supply container, with an end of the discharge passageway being positioned at a bottommost side of the developer supply container, and with the developer accommodating body being rotatable about a rotational axis thereof relative to the developer discharging body; and

    a track provided at each of opposite sides of the developer discharging body, each track being positioned (i) below a horizontal plane that includes the rotational axis and (ii) divides the developer supply container into a lower section that includes the discharge opening and an upper section, a surface of each track extending from a first position to a second position, with the second position being closer to the horizontal plane than the first position is to the horizontal plane, and with the surface facing upward, and each track extending such that a plane perpendicular to the rotational axis and passing through the track passes through the end of the discharge passageway when the discharge passageway through which developer is discharged to outside of the developer supply container is formed.
