Developer supply container and developer supplying system
There are provided a rotatable developer accommodating portion accommodating a developer, a discharge end portion provided at a bottom side with a discharge opening for discharging the developer accommodated in the developer accommodating portion, an engaging portion 30 engageable with a portion-to-be-engaged 11 b with a mounting operation of the developer supply container 1 to displace the portion-to-be-engaged 11 b in an upward direction U to bring the receiving opening into fluid communication with the discharge opening, and a swing shaft 41 rotatably supporting engaging portion 30 provided at such a position that opposite end portions of the engaging portion 30 a rotatable.
1. A developer supply container detachably mountable to a developer receiving apparatus, the developer receiving apparatus including a developer receiving portion having a receiving opening for receiving developer, and a portion-to-be-engaged integrally displaceable with the developer receiving portion, the developer supply container comprising:
developer;
a developer accommodating body accommodating the developer;
a gear configured to transmit a driving force to the developer accommodating body;
a developer discharging body in fluid communication with the developer accommodating body, the developer discharging body having a discharge opening configured to permit discharge of the developer in the developer accommodating body at a bottom side thereof, with the developer accommodating body being rotatable relative to the developer discharging body;
an engaging portion engageable with the portion-to-be-engaged with a mounting operation of the developer supply container to displace the developer receiving portion so as to move the receiving opening toward the discharge opening, thus bringing the receiving opening in fluid communication with the discharge opening;
a shaft portion which is provided between opposite end portions of the engaging portion with respect to a rotational axis direction of the developer accommodating body and which rotatably supports the engaging portion; and
a restricting portion configured to restrict movement of one end portion, which is closer to the gear, of the engaging portion with respect to the rotational axis direction, beyond a predetermined position.
2. A developer supply container according to claim 1 , wherein the shaft portion is disposed below a horizontal plane including a rotational axis of the developer accommodating body and above the discharge opening.
3. A developer supply container according to claim 1 , wherein-the shaft portion is disposed on a side surface of the developer discharging body, as seen in a direction in which the developer supply container is inserted.
4. A developer supply container according to claim 3 , wherein the shaft portion is disposed on each of side surfaces of the developer discharging body, as seen in the direction in which the developer supply container is inserted.
5. A developer supply container according to claim 1 , wherein the shaft portion is disposed at a position more remote from the gear than-the discharge opening.
6. A developer supply container according to claim 1 , wherein the engaging portion is disposed below a horizontal plane including a rotational axis of the developer accommodating body.
7. A developer supply container according to claim 1 , wherein the engaging portion is disposed on a side surface of the developer discharging body, as seen in a direction in which the developer supply container is inserted.
8. A developer supply container according to claim 7 , wherein the engaging portion is disposed on each of side surfaces of the developer discharging body, as seen in a direction in which the developer supply container is inserted.
9. A developer supplying system comprising:
(i) a developer receiving apparatus including developer receiving portion having a receiving opening configured to receive developer, and a portion-to-be-engaged integrally displaceable with the developer receiving portion;
(ii) a developer supply container detachably mountable to the developer receiving apparatus, the developer supply container including:
(ii-i) developer;
(ii-ii) a developer accommodating body accommodating the developer;
(ii-iii) a gear configured to transmit a driving force to the developer accommodating body;
(ii-iv) a developer discharging body in fluid communication with the developer accommodating body, the developer discharging body having a discharge opening configured to permit discharge of the developer in the developer accommodating body at a bottom side thereof, with the developer accommodating body being rotatable relative to the developer discharging body;
(ii-v) an engaging portion engageable with the portion-to-be-engaged with a mounting operation of the developer supply container to displace the developer receiving portion so as to move the receiving opening toward the discharge opening, thus bringing the receiving opening in fluid communication with the discharge opening;
(ii-vi) a shaft portion which is provided between one end portions of the engaging portion with respect to a rotational axis direction of the developer accommodating body and which rotatably supports the engaging portion; and
(ii-vii) a restricting portion configured to restrict movement of one end portion, which is closer to the gear, of the engaging portion with respect to the rotational axis direction, beyond a predetermined position.
