Abstract: A developer supply container includes a rotatable developer accommodating portion accommodating developer and a developer discharging portion in fluid communication with the developer accommodating portion, the developer discharging portion being provided with a discharge opening for discharging the developer from the developer accommodating portion. A seesaw member is provided at each of opposite lateral sides of the developer supply container, each seesaw member being positioned to not cover the discharge opening when the developer supply container is oriented with the developer discharge opening positioned at a bottom side of the developer discharging portion, with both of the seesaw members being rotatable about a second rotational axis that extends in a direction that crosses a direction of the first rotational axis.

Abstract: A developer supply container includes a developer accommodating body and a developer discharging body in fluid communication with the developer accommodating body. A track is positioned at a side of the developer discharging body, with the track including a surface that extends from a first position to a second position. When the developer supply container is oriented with the track positioned below a horizontal plane that includes a rotational axis of the developer accommodating body and a 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 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 an end of the discharge passageway.

Abstract: A developer supply includes a developer accommodating body and a developer discharging body. A track is positioned at a side of the developer discharging body, with the track including a surface that extends from a first position to a second position. When the developer supply container is oriented with the track and the shutter positioned below a horizontal plane that includes the rotational axis and a 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 a 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.
