Patent ID: 8463164

Claim:
A developer supply container detachably mountable to a developer receiving apparatus including a driving gear, said container comprising: a substantially cylindrical container configured to contain a developer, said cylindrical container having a developer discharging opening formed on a peripheral portion thereof; a developer feeding blade provided in said cylindrical container and configured to feed the developer in said cylindrical container toward said developer discharging opening by rotation thereof relative to said cylindrical container when said cylindrical container is positioned at a developer discharging position; a stepped gear engageable with the driving gear and rotatable about an axis thereof to receive a rotational force for rotating said developer feeding blade from the driving gear; a drive relaying gear, disposed co-axially with a rotation shaft for said developer feeding blade, configured and positioned to relay a drive transmission force between said stepped gear and said rotation shaft; a regulating projection configured and positioned to regulate a mounting attitude of said cylindrical container relative to the apparatus so as to prevent an engagement between said stepped gear and the driving gear, and thereafter upon mounting said cylindrical container, said stepped gear being revolvable, with manual rotation of said cylindrical container, in a setting direction about a rotation center of said cylindrical container to a set position where said stepped gear is engageable with the driving gear; and a load applier configured and positioned to apply a load to said stepped gear to rotate said cylindrical container from the set position to the developer discharging position by the rotational force received by said stepped gear.
