DEVELOPER SUPPLY CONTAINER AND DEVELOPER SUPPLYING SYSTEM
First Claim
1. A developer supply container detachably mountable to a developer receiving apparatus, the developer receiving apparatus including a developer receiving portion provided with a receiving port for receiving developer and including a portion-to-be-engaged capable of displacing integrally with the developer receiving portion, the developer supply container comprising:
- a rotatable developer accommodating portion for accommodating the developer;
a discharging portion provided at a bottom side thereof with a discharge opening for discharging the developer accommodated in the developer accommodating portion; and
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 in a displacing direction so as to bring the receiving port into fluid communication with the discharge opening,wherein the engaging portion has such a shape that a first angle relative to a mounting direction of the developer supply container at a downstream end portion in the mounting direction is larger than a second angle relative to the mounting direction at an upstream end portion in the mounting direction.

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 11b capable 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 accommodating in the developer accommodating portion, and an engaging portion 30. The engaging portion 30 engages with the portion-to-be-engaged 11b 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 30 includes a curved portion 3b 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.
