If a user is not familiar with the operation for a developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. By increasing a rotation load of a second gear which is in an operable connection with a drive gear member of the developer receiving apparatus by a function of a locking member, the developer supply container mounted to the developer receiving apparatus is rotated toward the supply position. After the developer supply container rotates to the supply position, the locking by the locking member is released, by which the rotation load applied to the second gear is reduced, so that drive transmission, thereafter, to the feeding member for developer supply is smooth.

The invention claimed is: 1. A developer supply container detachably mountable to a developer receiving apparatus, said developer supply container comprising: an accommodating portion for accommodating a developer; a discharging member for discharging a developer from said accommodating portion; a drive transmission member, engageable with a driving member of said developer receiving apparatus, for transmitting a driving force to said discharging member; and suppressing means having a variable suppressing force for suppressing a relative rotation between said developer supply container and said drive transmission member. 2. A developer supply container according to claim 1, wherein said drive transmission member is rotatably supported at a position away from a rotational center of said developer supply container. 3. A developer supply container according to claim 1, wherein said suppressing means includes an applying portion for applying a rotation load to said drive transmission member. 4. A developer supply container according to claim 3, further comprising a drive relaying member for relaying a drive transmission between said drive transmission member and said discharging member, wherein said applying portion applies a rotation load to said drive transmission member through said drive relaying member. 5. A developer supply container according to claim 1, further comprising a reducing portion for reducing a suppressing force of said suppressing means. 6. A developer supply container according to claim 5, further comprising a drive relaying member for relaying a drive transmission between said drive transmission member and said discharging member, wherein said reducing portion is provided on said drive relaying member which is rotatable relative to said developer supply container rotated to an operating position by the suppressing force of said suppressing means. 7. A developer supply container according to claim 1, wherein said suppressing means includes a locking portion for locking said drive transmission member. 8. A developer supply container according to claim 7, wherein when said developer supply container rotates to an operating position, said drive transmission member is released by releasing means of said developer receiving apparatus. 9. A developer supply container according to claim 7, further comprising a drive relaying member for relaying a drive transmission between said drive transmission member and said discharging member, wherein said locking portion locks said drive transmission member through said drive relaying member. 10. A developer supply container according to claim 1, wherein a rotation load of said drive transmission member in a state of being suppressed by said suppressing means is larger than a rotation resisting force received from said developer receiving apparatus by said developer supply container, and a rotation load of said drive transmission member after the suppressing force of said suppressing means is changed is smaller than the rotation resisting force received from said developer receiving apparatus by said developer supply container. 11. A developer supply container according to claim 1, wherein a rotation load of said drive transmission member in a state of being suppressed by said suppressing means is not less than 0.05 Nm and not more than 1.0 Nm, and the rotation load of said drive transmission member after the suppressing force of said suppressing means is changed is less than 0.05 Nm. 12. A developer supply container according to claim 1, further comprising an engaging portion engageable with a shutter for opening and closing a developer receiving opening of the developer receiving apparatus, wherein said engaging portion moves said shutter in an opening direction in interrelation with rotation of said developer supply container toward an operating position by the suppressing force of said suppressing means. 13. A developer supply container according to claim 12, further comprising a developer discharge opening in a peripheral surface of said accommodating portion, wherein said developer discharge opening is brought into communication with the developer receiving opening in interrelation with rotation of said developer supply container toward the operating position. 14. A developer supply container according to claim 1, wherein said drive transmission member includes a teeth portion for meshing engagement with a teeth portion of the driving member.
