Abstract

A developer supply container includes a developer accommodating portion having one end provided with an opening, and drive receiving portion, a discharging portion including a receiving portion into which the one end of the accommodating portion is inserted, and a developer discharge opening, the accommodating portion being mounted to the discharging portion rotatably relative to the discharging portion; a sealing member sealing between the one end and the receiving portion; a projection radially projecting from an outer peripheral surface of the accommodating portion; and a first restricting portion and a second restricting portion provided on the receiving portion of the discharging portion at positions upstream and downstream of the projection, respectively in the inserting direction and contactable to the projection to restrict an inclination of the rotational axis of the accommodating portion relative to the inserting direction within a predetermined range.

Claims (11)

1. A developer supply container comprising:

an accommodating portion having an inside wall provided with a helical projection that is capable of feeding developer, the accommodating portion including a first cylindrical portion provided with a circular rib forming a circular opening through which the developer is fed by the helical projection;

a discharging portion capable of discharging the developer, the discharging portion including (i) a second cylindrical portion provided with a receiving opening capable of receiving the developer passed through the circular opening, wherein the first cylindrical portion is inserted into the second cylindrical portion such that the accommodating portion is rotatable relative to the discharging portion and the developer is capable of being fed from the circular opening into the receiving opening, and (ii) a discharge chamber provided with a discharge opening through which the developer received from the accommodating portion through the receiving opening is discharged to outside of the developer supply container;

a gear provided on the accommodating portion and configured to receive a driving force for rotating the accommodating portion relative to the discharge opening, the gear being provided between the circular rib and the helical projection in a rotational axis direction of the accommodating portion; and

a sealing member elastically deformed by being sandwiched by the receiving opening and an end surface of the circular rib in the rotational axis direction,

wherein the accommodating portion is further provided with an annular projection projecting from the first cylindrical portion between the end surface of the circular rib and the gear,

wherein the discharge portion is further provided with an engaging claw provided between the annular projection and the gear,

wherein an engaging portion is provided between the annular projection and the end surface of the circular rib in the rotational axis direction, and

wherein the annular projection is positioned so as to be sandwiched between the engaging claw and the engaging portion, with a gap provided between the annular projection and the engaging portion by the annular projection contacting the engaging claw that is more than 0.1 mm and not more than 0.4 mm.

2. A developer supply container according to claim 1 , wherein the engaging claw locks the annular projection so as to prevent the first cylindrical portion of the accommodating portion from disengaging from the second cylindrical portion of the discharging portion.

3. A developer supply container according to claim 1 , wherein the second cylindrical portion of the discharging portion is provided with a hole at a position that is towards the engaging portion from the engaging claw.
