Abstract:
1. A developer supply container detachably mountable to a developer receiving apparatus and settable in the developer receiving apparatus by a setting operation including at least a rotation of said developer supply container in a setting direction, wherein the developer receiving apparatus includes a driving gear rotatable in a direction opposite to the setting direction, said developer supply container comprising: an inner cylindrical portion, provided with an opening, for containing a developer; an outer cylindrical portion, provided with an opening which is in fluid communication with the opening of said inner cylindrical portion, rotatably around an outside of said inner cylindrical portion; a rotatable developer discharging member for discharging the developer out of said inner cylindrical portion when said outer cylindrical portion takes a developer discharging position; a regulating portion for regulating an attitude of said developer supply container relative to the developer receiving apparatus to a first attitude where the opening of said outer cylindrical portion is oriented upwardly; a stopping portion for stopping the rotation of said outer cylindrical portion with the setting operation to a second attitude where the opening of the outer cylindrical portion is oriented sidewardly; and a drive transmitting means for receiving a rotating force from the driving gear rotating in the opposite direction and for transmitting the rotational force to said developer discharging member, wherein the rotating force received by said drive transmission means is effective to rotate, in the opposite direction, said developer discharging member relative to said outer cylindrical portion taking the second attitude, by which a peripheral movement of said developer discharging member is upward adjacent to the opening of said outer cylindrical portion, and is also effective to urge said outer cylindrical portion to said stopping portion.
