What is claimed as new and desired to be protected by Letters Patent of the United States is: 1. A powder container, comprising: an upper section configured to store powder; a lower section, connected to the upper section, configured to discharge powder, the lower section having a trapezoid-shaped cross-section, a width of the trapezoid-shaped cross-section at an upper portion being greater than a width of the trapezoid-shaped cross-section at a lower portion, the lower section including an opening in the trapezoid-shaped cross-section which discharges powder in a direction perpendicular to the trapezoid-shaped cross-section; and a shutter for sealing and unsealing said opening. 2. A powder container according to claim 1, wherein: both sides of the trapezoid-shaped cross-section have an indentation. 3. A powder container according to claim 2, wherein: the indentation of each side of the trapezoid-shaped cross-section is semi-circular in shape. 4. A powder container according to claim 2, further comprising: toner. 5. A powder container according to claim 1, wherein: said shutter has a cylindrical shape. 6. A powder container according to claim 1, wherein the lower section comprises: an opening which faces the upper section configured to receive powder from the upper section. 7. A powder container according to claim 1, further comprising: a second opening disposed opposite to said opening. 8. A powder container according to claim 1, further comprising: toner. 9. A powder container according to claim 1, wherein: the upper section comprises a flexible bag. 10. A powder container, comprising: an upper section configured to store powder; a lower section, connected to the upper section, configured to discharge powder, the lower section having a trapezoid-shaped cross-section, a width of the trapezoid-shaped cross-section at an upper portion being greater than a width of the trapezoid-shaped cross-section at a lower portion, the lower section comprising: an inner unit; and an outer unit which at least partially surrounds the inner unit. 11. A powder container according to claim 10, wherein: the inner unit has an opening at a top thereof and an opening at a side thereof. 12. A powder container according to claim 11, wherein: the outer unit includes an opening at a top thereof and an opening at a side thereof. 13. A powder container according to claim 12, wherein: the opening at the top of the inner unit corresponds to the opening of the top of the outer unit; and the opening at the top of the inner unit corresponds to the opening of the top of the outer unit. 14. A powder container according to claim 13, further comprising; an o-ring disposed between the inner and outer units at the opening of the side of the outer unit. 15. A powder container according to claim 14, further comprising: a shutter which is slidably disposed inside the o-ring. 16. A powder container, comprising: an upper section configured to store powder; means for dispensing powder and for sealing the powder container, connected to the upper section, configured to discharge powder, the means having a trapezoid-shaped cross-section, a width of the trapezoid-shaped cross-section at an upper portion being greater than a width of the trapezoid-shaped cross-section at a lower portion, the means including an opening in the trapezoidal-shaped cross-section which discharges powder in a direction perpendicular to the trapezoidal-shaped cross-section; and a shutter for sealing and unsealing said opening. 17. A powder container according to claim 16, wherein: both sides of the trapezoid-shaped cross-section have an indentation. 18. A powder container according to claim 17, wherein: the indentation of each side of the trapezoid-shaped cross-section is semi-circular in shape. 19. A powder container according to claim 17, further comprising: toner. 20. A powder container according to claim 16, wherein: said shutter has a cylindrical shape. 21. A powder container according to claim 16, wherein the means comprises: an opening which faces the upper section configured to receive powder from the upper section. 22. A powder container according to claim 16, further comprising: a second opening disposed opposite to said opening. 23. A powder container according to claim 16, further comprising: toner. 24. A powder container according to claim 16, wherein: the upper section comprises a flexible bag. 25. A powder container, comprising: an upper section configured to store powder; and means for dispensing powder and for sealing the powder container, connected to the upper section, configured to discharge powder, the means having a trapezoid-shaped cross-section a width of the trapezoid-shaped cross-section at an upper portion being greater than a width of the trapezoid-shaped cross-section at a lower portion, the means including: an inner unit; and an outer unit which at least partially surrounds the inner unit. 26. A powder container according to claim 25, wherein: the inner unit has an opening at a top thereof and an opening at a side thereof. 27. A powder container according to claim 26, wherein: the outer unit includes an opening at a top thereof and an opening at a side thereof. 28. A powder container according to claim 27, wherein: the opening at the top of the inner unit corresponds to the opening of the top of the outer unit; and the opening at the top of the inner unit corresponds to the opening of the top of the outer unit. 29. A powder container according to claim 28, further comprising; an o-ring disposed between the inner and outer units at the opening of the side of the outer unit. 30. A powder container according to claim 29, further comprising: a shutter which is slidably disposed inside the o-ring. 31. A powder container, comprising: an upper section configured to store powder; a lower section configured to discharge powder, the lower section having a cross-section with a shape such that a width of an upper edge of the cross-section is greater than a width of a lower edge of the cross-section, the lower section including an opening in the cross-section which discharges powder in a direction perpendicular to the cross-section; and a shutter for sealing and unsealing said opening. 32.
