Developer supply container
A developer supply container 1 detachably mountable to a developer supplying apparatus 201 includes a developer accommodating portion 2 capable of accommodating a developer, a discharge opening 4 a for discharging the developer accommodated in the developer accommodating portion 2 toward the developer supplying apparatus 201 , a pump portion 3 a for effecting a discharging operation through the discharge opening 4 a , a communicating portion 4 d provided at a position contacting the discharge opening 4 a and capable of storing a constant amount of the developer, and a regulating portion 7 capable of taking a developer flow regulating state in which the flow of the developer into the communicating portion 4 d and a developer flow non-regulating state in which the entering of the developer is not regulated, the regulating portion 7 taking the developer flow regulating state in a discharging operation of the pump portion 3 a , wherein the regulating portion 7 is provided with an air flow path 7 g for communicating between the communicating portion 4 d and the pump portion 3 a.
1. A developer supply container comprising:
a developer accommodating body configured to contain developer; and
a developer discharging body in fluid communication with the developer accommodating body, the developer discharging body including a discharging passageway through which the developer may be discharged to outside of the developer supply container, the discharging passageway including (i) an entrance port provided inside of the developer discharging body and configured to receive the developer, and (ii) a discharge port configured to discharge the developer to outside of the developer supply container, with the developer accommodating body being rotatable relative to the developer discharging body about a rotational axis; and
a rotatable member provided in the developer discharging body and rotatable about the rotational axis, the rotatable member including a plurality of extending portions extending radially with respect to the rotational axis, the radially extending portions each including a radially outside end portion, with each outside end portion having a dimension, as measured in the direction of the rotational axis, such that the outside end portion at least partly overlaps the entrance port, as viewed in a direction perpendicular to the rotational axis.
2. A developer supply container according to claim 1 , wherein the rotatable member is integrally rotatable with the developer accommodating body.
3. A developer supply container according to claim 1 , wherein the radially outside end portions pass through an upper space above the entrance port in association with rotation of the rotatable member.
4. A developer supply container according to claim 1 , further comprising:
a fluid communication passageway in fluid communication with an inside of the developer accommodating body; and
a feeding member provided in the fluid communication passageway and configured to feed the developer from the developer accommodating body to the developer discharging body,
wherein the feeding member is integrally provided with the rotatable member.
