Developer supply container and developer supplying system

A developer supply container comprising:

• a developer accommodating body configured to contain developer;
• 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;
• a shutter movable relative to the developer discharging body in a direction of the rotational axis, with the shutter being movable between an open position where the discharge opening is open and a closed position where the discharge opening is closed by the shutter;
• and
• a track positioned at a side of the developer discharging body, the track including a surface that extends from a first position to a second position,
• wherein, when (i) the developer supply container is oriented with the track and the shutter positioned below a horizontal plane that includes the rotational axis and divides the developer supply container into a lower section that includes the discharge opening and an upper section and (ii) the discharge passageway through which developer is discharged to outside of the developer supply container is formed at the bottommost side of the developer supply container, the track is positioned between the horizontal plane and the shutter in a direction perpendicular to the horizontal plane, the second position is closer to the horizontal plane than the first position is to the horizontal plane, the surface faces upward, and the track extends such that a plane perpendicular to the rotational axis and passing through the track passes through the end of the discharge passageway.

• a gear portion configured to receiving a force to rotate the developer accommodating body relative to the developer discharging body;
• a shutter movable relative to the developer discharging body in a direction of the rotational axis, with the shutter being movable between an open position where the discharge opening is open and a closed position where the discharge opening is closed by the shutter;
