Abstract

A developer supplying container includes a rotary cylindrical accommodating portion including an opening portion formed at one end portion of the accommodating portion in a rotation-axis direction, and a developer discharging portion including a connection portion and a discharging outlet. The connection portion includes a first separation portion and a second separation portion separated from each other in a direction intersecting with the rotation-axis direction. The accommodating portion includes a first engaging portion formed in an outer circumferential surface of the one end portion covered by the connection portion. At least one of the first separation portion and the second separation portion includes a second engaging portion configured to engage with the first engaging portion when the one end portion of the accommodating portion is covered by the connection portion, and prevent the connection portion from being disconnected from the accommodating portion in the rotation-axis direction.

Claims (16)

1. A developer supplying container comprising:

a rotary cylindrical accommodating portion including an opening portion formed at one end portion of the accommodating portion in a rotation-axis direction, the accommodating portion being configured to receive rotational driving force and rotate such that developer accommodated in the accommodating portion is conveyed toward the one end portion; and

a developer discharging portion including a connection portion and a discharging outlet, the connection portion being a portion that is disposed to cover around the one end portion of the accommodating portion and to which the accommodating portion is connected relatively rotatably with respect to the developer discharging portion, the discharging outlet being configured to discharge developer supplied from the opening portion of the accommodating portion,

wherein the connection portion includes a first separation portion and a second separation portion configured to be separated from each other in a direction intersecting with the rotation-axis direction of the accommodating portion, and a connect engaging portion configured to detachably attach the second separation portion to the first separation portion,

wherein the accommodating portion includes a first engaging portion formed in an outer circumferential surface of the one end portion covered by the connection portion, and

wherein at least one of the first separation portion and the second separation portion includes a second engaging portion configured to engage with the first engaging portion in a state where the one end portion of the accommodating portion is covered by the connection portion, and prevent the connection portion from being disconnected from the accommodating portion in the rotation-axis direction.

2. The developer supplying container according to claim 1 , wherein a length of the second separation portion in a circumferential direction is equal to a length of the first separation portion in the circumferential direction.

3. The developer supplying container according to claim 1 ,

wherein a length of the second separation portion in a circumferential direction is shorter than a length of the first separation portion in the circumferential direction, and

wherein the second engaging portion is formed on the second separation portion and is not formed on the first separation portion.

4. The developer supplying container according to claim 1 ,

wherein the first engaging portion is formed in a recessed shape, and

wherein the second engaging portion is formed in a projected shape.

5. The developer supplying container according to claim 1 , wherein the second engaging portion is formed on an inner circumferential surface of the second separation portion such that the second engaging portion extends in a circumferential direction.

6. The developer supplying container according to claim 1 , wherein the connect engaging portion includes a flexible engaging hook formed on one of the first separation portion and the second separation portion, and an engaging hole portion formed in another of the first separation portion and the second separation portion and configured to engage with the engaging hook.

7. The developer supplying container according to claim 1 , wherein the connect engaging portion includes a screw, a through-hole portion, and a screw hole portion, the through-hole portion being formed in one of the first separation portion and the second separation portion and having a diameter that allows a shaft portion of the screw to pass through the one of the first separation portion and the second separation portion, and that does not allow a head portion of the screw to pass through the one of the first separation portion and the second separation portion, the screw hole portion being a hole which is formed in another of the first separation portion and the second separation portion and to which the screw is fastened.
