1. A developer supply container detachably mountable to an image forming apparatus, said developer supply container comprising:a main body for accommodating a developer; a discharge opening, provided in the main body, for permitting discharge of the developer; a shutter member for opening and closing said discharge opening; a rotatable member which is rotatable relative to the main body to effect opening and closing movement of said shutter member; a regulating member for limiting a rotation of said rotatable member in a direction of opening said shutter member, wherein said regulating member includes an extended portion integral with said rotatable member and extended substantially along the opening rotational direction of said rotatable member and a limiting projection, projected from said extended portion toward said main assembly, for abutment to a stopper projection of the main body, wherein said regulating member has an abutting portion for abutment to an image forming apparatus in a mounting operation of said developer supply container, and said limiting projection displaces to a position where it is incapable of abutting said stopper projection. 2. A container according to claim 1, wherein before said developer supply container is set in said image forming apparatus, said regulating member limits rotation of said rotatable member without said extended portion receiving a force in the mounting direction.3. A container according to claim 1, wherein said abutting portion is disposed adjacent a free end portion with respect to a direction of extension of said extended portion.4. A container according to claim 1, wherein said extended portion includes a displacement prevention portion for preventing radially inward displacement of said rotatable member.5. A container according to claim 1, wherein said regulating member is integrally molded from a resin material together with said rotatable member.6. A container according to claim 1, further comprising a limiting projection, projected from said extended portion toward the main body, for abutment to a stopper projection to limit a rotation of rotatable member in the direction of closing said shutter member.7. A container according to claim 1, wherein said rotatable member includes a first gear portion for meshing engagement with a first gear member provided in said image forming apparatus, and a second gear portion for meshing engagement with a second gear member which is provided in said image forming apparatus and which is rotatable with said first gear member, wherein by mounting said developer supply container to said image forming apparatus, a driving connection is established between said first gear portion and said second gear portion through said first gear member and said second gear member.8. A container according to claim 7, wherein a drive transmission path between said first gear portion and said second gear portion is disconnected before said developer supply container is mounted to said image forming apparatus.9. A developer supply container removably settable in an image forming apparatus, said developer supply container comprising:a main body for accommodating a developer; a discharge opening, provided in the main body, for permitting discharge of the developer; a shutter member for opening and closing said discharge opening; a rotatable grip member which is rotatable relative to the main body to open and close said shutter member; a regulating member for regulating a rotation of said grip member before said developer supply container is set in said image forming apparatus; wherein said regulating member is integrally molded from a resin material together with said grip member. 10. A container according to claim 9, wherein said rotatable member includes a first gear portion for meshing engagement with a first gear member provided in said image forming apparatus, and a second gear portion for meshing engagement with a second gear member which is provided in said image forming apparatus and which is rotatable with said first gear member, wherein by mounting said developer supply container to said image forming apparatus, a driving connection is established between said first gear portion and said second gear portion through said first gear member and said second gear member.11. A container according to claim 10, wherein a drive transmission path between said first gear portion and said second gear portion is disconnected before said developer supply container is set in said image forming apparatus.
