A developer supply container is detachably mountable to a developer receiving apparatus, the developer receiving apparatus including a developer receiving portion provided with a receiving port for receiving a developer and including a portion-to-be-engaged of displacing integrally with the developer receiving portion. The developer supply container includes a discharging portion provided with a shutter opening for discharging the developer accommodated in the developer accommodating portion, and an engaging portion. The engaging portion engages with the portion-to-be-engaged with a mounting operation of the developer supply container to displace the developer receiving portion so as to bring the receiving opening into fluid communication with the shutter opening. The engaging portion includes a curved portion having an angle relative to a mounting direction of the developer supply container, the angle decreasing with approach toward an upstream side in the mounting direction.

Developer supply container and developer supplying system

A developer supply container includes a developer accommodating portion accommodating developer, and a developer discharging portion in fluid communication with the developer accommodating portion. The developer accommodating portion is rotatable about a rotational axis and relative to the developer discharging portion, with the developer discharging portion being provided with a developer discharge opening at a bottommost side of the developer discharging portion and configured to permit discharging the developer to outside of the developer supply container. A lifter is linearly liftable relative to the developer discharging portion in a direction perpendicular to a horizontal plane that includes the rotational axis when the developer supply container is oriented with the developer discharge opening positioned at a bottom side of the developer discharging portion.

A developer supply container includes a developer accommodating body configured to accommodate developer, with the developer accommodating portion being provided with a gear portion. The developer supply container also includes a developer discharging body in fluid communication with the developer accommodating body, with the developer accommodating body being rotatable about a rotational axis thereof relative to the developer discharging body. A track is provided at each of opposite sides of the developer discharging body, each track including a fixed portion fixed on the discharging body and an elastically deformable portion extending from the fixed portion to a free end portion that is displaceable from the discharging body such that the elastically deformable portion intersects a horizontal plane that is parallel to the rotational axis.

With a mounting operation of a supply container, a supported portionof a developer receiving portionis supported by a receipt supporting portionof a lifting portion. With further mounting operation, a shutter sliding portionof the lifting portionslides on a shutter inclined portionof a shutter. The developer receiving portionis displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter, the lifting portionsupporting the supported portionof the developer receiving portion. By this, a load required for movement of the developer receiving portionis reduced to achieve smooth mounting of the supply container.

A developer supply container includes a developer accommodating body, a developer discharging body, a storing portion, provided a pump portion capable of changing a volume thereof with a reciprocating operation, and a rotatable member including a plurality of blades. The number of said blades is not less twice the number of times, per rotation of the rotatable member, of the reciprocating operation of the pump portion.
