What is claimed is: 1. A heating body comprising: a lead rod that conducts electricity from an external power source; a supporting member connected to the lead rod, the supporting member having a predetermined supporting force; a plurality of heaters, each coiled around the supporting member, having different thermal expansion coefficients, respectively, the plurality of heaters including first and second heating members, the first heating member disposed at an outside of the second heating member, the second heating member disposed around the supporting member such that the second heating member is disposed closer to the supporting member than the first heating member, the first heating member having a relatively higher thermal expansion coefficient than the second heating member; and a tube in which the heaters are disposed, wherein at least one of the plurality of heaters supports at least one other heater, wherein the tube is formed in a hollow shape, and the heaters are spaced apart from an innermost internal side of the tube to form an empty space between an external side of the plurality of heaters and the innermost internal side of the tube. 2. The heating body according to claim 1, wherein the plurality of heaters crosses one another. 3. The heating body according to claim 1, wherein at least one of the plurality of heaters has a straight line shape. 4. The heating body according to claim 3, wherein the straight line-shaped heater supports at least one other heater. 5. The heating body according to claim 1, wherein at least one of the plurality of heaters is coiled a predetermined number of times. 6. The heating body according to claim 1, wherein each of the plurality of heaters is coiled a predetermined number of times. 7. The heating body according to claim 1, wherein the plurality of heaters are adhered to one another. 8. The heating body according to claim 1, wherein one of the plurality of heaters is formed of carbon, and at least one other heater is formed of one of tungsten and a nickel/chrome-based alloy. 9. The heating body according to claim 1, wherein the tube has one of a linear shape, an omega (Ω) shape, and a “U” shape. 10. The heating body according to claim 1, wherein each of the first and second heating members are coiled in the same direction around the supporting member. 11. A heating body comprising: a lead rod that conducts from an external power source; a supporting member connected to the lead rod, the supporting member having a predetermined supporting force; a plurality of heaters having different thermal expansion coefficients, respectively, wherein the first heating member is coiled around the supporting member such that an inside coiled surface of the first heating member is spaced apart from an outside surface of the supporting member, and wherein the second heating member is coiled around the supporting member and an outside coiled surface of the second member has a diameter less than a diameter of the inside coiled surface of the first heating member; and a tube in which the heaters are disposed, wherein the tube is formed in a hollow shape, and the heaters are spaced apart from an innermost internal side of the tube to form an empty space between an external side of the plurality of heaters and the innermost internal side of the tube. 12. The heating body according to claim 11, wherein one of the plurality of heaters is coiled to surround an outside of at least one other heater. 13. The heating body according to claim 11, wherein the plurality of heaters cross one another at least once, and one of the crossing heaters supports at least one other crossed heater. 14. The heating body according to claim 11, wherein the plurality of heaters cross one another at least once, and the plurality of heaters are adhered to one another. 15. The heating body according to claim 11, wherein each of the plurality of heaters is coiled a predetermined number of times. 16. The heating body according to claim 11, wherein each of the first and second heating members are coiled in the same direction around the supporting member. 17. A heating body comprising: a lead rod that conducts from an external power source; a supporter connected to the lead rod, the supporter having a predetermined supporting force; a plurality of heaters having different thermal expansion coefficients, respectively, the plurality of heaters including first and second heating members, the first heating member disposed at an outside of the second heating member, the second heating member disposed around the supporter such that the second heating member is disposed closer to the supporter than the first heating member, the first heating member having a relatively higher thermal expansion coefficient than the second heating member; and a tube in which the heaters are disposed; wherein the supporter supports at least one heater, wherein the tube is formed in a hollow shape, and the heaters are spaced apart from an innermost internal side of the tube to form an empty space between an external side of the plurality of heaters and the innermost internal side of the tube. 18. The heating body according to claim 17, wherein the heater is coiled to surround the supporter. 19. The heating body according to claim 17, wherein each of the first and second heating members are coiled in the same direction around the supporter.
