Abstract: With a mounting operation of a supply container, a supported portion 11b of a developer receiving portion 11 is supported by a receipt supporting portion 30c of a lifting portion 30. With further mounting operation, a shutter sliding portion 30b of the lifting portion 30 slides on a shutter inclined portion 4f of a shutter 4. The developer receiving portion 11 is displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter 4, the lifting portion 30 supporting the supported portion 11b of the developer receiving portion 11. By this, a load required for movement of the developer receiving portion 11 is reduced to achieve smooth mounting of the supply container.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A developer supply container is detachably mountable to a developer receiving apparatus including a developer receiving portion provided with a receiving opening for receiving a developer, and a portion-to-be-engaged 11b integrally displaceable 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. An operation portion 21 displaces the developer receiving portion to bring the receiving opening into communication with the shutter opening by engagement between the engaging portion 21d and the portion-to-be-engaged 11b by a predetermined operation executed after the developer supply container is mounted to a predetermined position of the developer receiving apparatus.

Abstract: With a mounting operation of a supply container, a supported portion 11b of a developer receiving portion 11 is supported by a receipt supporting portion 30c of a lifting portion 30. With further mounting operation, a shutter sliding portion 30b of the lifting portion 30 slides on a shutter inclined portion 4f of a shutter 4. The developer receiving portion 11 is displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter 4, the lifting portion 30 supporting the supported portion 11b of the developer receiving portion 11. By this, a load required for movement of the developer receiving portion 11 is reduced to achieve smooth mounting of the supply container.

Abstract: An image forming apparatus includes an attachment portion, an attachment detection unit, an output portion, a first cover, a first detection portion, a second cover, and a control unit. A control unit is configured to control opening movement of the first cover to open the first cover linked with movement that the second cover is opened when the output portion outputs information of replacing the developer accommodating container. After the first detection portion detects that the first cover is in a closed state after the first cover has been opened based on information output by the output portion, the first detection portion detects whether the developer accommodating container is attached to the attachment portion or not, and if the first detection portion detects that the developer accommodating container is not attached to the attachment portion, the control unit controls the first cover to open.

Abstract: A developer container storage apparatus includes a storage portion, a door, a locking member, a lock urging portion, a driving source, a rotation shaft, a cylindrical sleeve, and an engage portion. When the door is in the close state, the rotation shaft is located at the engage position, and if the rotation shaft rotates, the engage portion switches the locking member from the first position to the second position so that the door is made unlockable in the close state. When the door is in an open state, the rotation shaft is located at the disengage position, and the lock urging portion switches the locking member from the second position to the first position so that the door is made lockable in the close state.
