What is claimed is: 1. A developer supply container detachably mountable to a developer receiving apparatus having a receiving opening for receiving a developer, an apparatus shutter for opening and closing said receiving opening, said developer supply container comprising: a container body for containing the developer, said container body including a discharge opening for discharging the developer; a container shutter for opening and closing said discharge opening by a rotational movement of said container body with said container shutter being prevented from moving by said developer receiving apparatus; and an interrelating portion for interrelating the rotational movement of the apparatus shutter with said container body such that the apparatus shutter starts moving when a neighborhood of a leading, with respect to a moving direction thereof, end of said discharge opening exposed by said container shutter, is substantially aligned with a neighborhood of a trailing end of the apparatus shutter. 2. A developer supply container according to claim 1, wherein the neighborhood of the leading end is in a range of 5 mm from the trailing end of the apparatus shutter. 3. A developer supply container according to claim 1, wherein an engaging relation between said interrelating portion, the apparatus shutter is maintained so that when said container body is moving, the neighborhood of the leading end of the discharge opening is kept substantially aligned with the neighborhood of the trailing end of the apparatus shutter. 4. A developer supply container according to claim 3, wherein said interrelating portion limits movement of said container body by the apparatus shutter being limited by a stopper provided in the developer receiving apparatus. 5. A developer supply container according to claim 1, wherein said interrelating portion interrelates said container body with the rotational movement of the apparatus shutter in an opposite direction such that when said discharge opening, said receiving opening are resealed after a state in which they are in communication with each other, the apparatus shutter substantially completely closes said receiving opening while the trailing end of the discharge opening is kept substantially aligned with the leading end of the apparatus shutter. 6. A developer supply container according to claim 5, wherein said interrelating portion interrelates said container body with the rotational movement of the apparatus shutter in an opposite direction such that neighborhood of the trailing end of said discharge opening enters said container shutter substantially simultaneously with the apparatus shutter substantially completely closes said receiving opening. 7. A developer supply container according to claim 1, wherein said interrelating portion is projected for a peripheral surface of said container body. 8. A developer supply container according to claim 7, wherein said interrelating portion has a snap-fit structure portion for effecting a snap-fit connection with the apparatus shutter. 9. A developer supply container according to claim 1, wherein said container body is generally cylindrical. 10. A developer supply container detachably mountable to a developer receiving apparatus having a receiving opening for receiving a developer, an apparatus shutter for opening and closing said receiving opening, said developer supply container comprising: a container body for containing the developer, said container body including a discharge opening for discharging the developer; a container shutter for opening and closing said discharge opening by a rotational movement of said container body with said container shutter being prevented from moving by said developer receiving apparatus; an interrelating portion for interrelating said container body with a rotational movement of the apparatus shutter such that when said discharge opening and said receiving opening are resealed after a state in which they are in communication with each other, the apparatus shutter substantially completely closes said receiving opening while the trailing, with respect to a moving direction thereof, end of the discharge opening is kept substantially aligned with the leading end of the apparatus shutter. 11. A developer supply container according to claim 10, wherein said interrelating portion starts movement of the apparatus shutter when the trailing end is in a range of 5 mm from the leading end of the apparatus shutter. 12. A developer supply container according to claim 11, wherein said interrelating portion interrelates said container body with the rotational movement of the apparatus shutter in an opposite direction such that neighborhood of the trailing end of said discharge opening enters said container shutter substantially simultaneously with the apparatus shutter substantially completely closes said receiving opening. 13. A developer supply container according to claim 10, wherein said interrelating portion is projected for a peripheral surface of said container body. 14. A developer supply container according to claim 13, wherein said interrelating portion has a snap-fit structure portion for effecting a snap-fit connection with the apparatus shutter. 15. A developer supply container according to claim 10, wherein said container body is generally cylindrical. 16. A developer supply container detachably mountable to a developer receiving apparatus having a receiving opening for receiving a developer, an apparatus shutter for opening and closing said receiving opening, said developer supply container comprising: a container body for containing the developer, said container body including a discharge opening for discharging the developer; an engaging portion, engageable with the apparatus shutter, for unsealing the apparatus shutter by a rotational movement of said container body in a first rotational direction, for resealing the apparatus shutter by a rotational movement of said container body in a second rotational direction which is opposite to the first rotational direction, wherein said engaging portion includes a snap-fit structure portion for effecting a releasable snap-fit connection with the apparatus shutter. 17. A developer supply container according to claim 16, wherein said engaging portion presses the apparatus shutter down with the movement of said container body in the first rotational direction, and pulls the apparatus shutter up with the movement of said container body in the second rotational direction. 18. A developer supply container according to claim 16, further comprising a container shutter for opening and closing said discharge opening by the rotational movement of said container body while the rotational movement is limited by the developer receiving apparatus.
