Abstract

Claims (10)

1. 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 gear portion provided with the developer accommodating body, the gear portion being provided about the rotational axis; and

a track provided at a side of the developer discharging body, the track being positioned below a horizontal plane that includes the rotational axis, the track including (i) a first surface that extends from a first position to a second position, with the second position being closer to the gear portion in a direction of the rotational axis than the first position is to the gear portion in the direction of the rotational axis, with the first surface ascending such that the second position is closer to the horizontal plane than the first position is to the horizontal plane, and with the first part having a surface facing upward, and (ii) a second surface extending from a third position to a fourth position such that a plane perpendicular to the rotational axis and passing through the second surface crosses the end of the discharge passageway when the discharge passageway through which developer is discharged to outside of the developer supply container is formed, with the third position being closer to the gear portion in a direction of the rotational axis than the second position is to the gear portion in the direction of the rotational axis, and with the fourth position being closer to the gear portion in a direction of the rotational axis than the third position is to the gear portion in the direction of the rotational axis, and (iii) a third surface provided above the second position and the third position at a position between the first surface and the second surface in the direction of the rotational axis,

wherein the track includes a part that descends from the third surface toward the second position and a part that descends to the third position from the third surface, and

wherein the track protrudes from the developer discharging body, and the track includes a first part including the first surface and the third surface and a second part including the second surface,

wherein the first part and the second part are separated with each other.

2. A developer supply container according to claim 1 , wherein the part of the track that descends from the third surface to the second position is an inclined surface that descends toward the second position and connects to the first surface at the second position.

3. A developer supply container according to claim 1 , wherein the second surface is horizontal, and the part of the track that descends from the third surface to the second position is above the third position.
