1. A device to prevent fire of a fusing belt having a heater positioned inside, the device comprising:
at least one temperature control member adjacent to one side of the fusing belt and, when the at least one temperature control member detects abnormal heat from the fusing belt based on a temperature of the fusing belt, the at least one temperature control member to cut off a supply of electricity to the heater to prevent the fire; and
a heat absorption member to absorb latent heat from the fusing belt to lower the temperature of the fusing belt to prevent the fire, wherein the at least one temperature control member and the heat absorption member are at the same interval with respect to an outer surface of the fusing belt,
wherein the heat absorption member is located entirely on an opposite side of the temperature control member with respect to a center of the fusing belt in an axial direction of the fusing belt.
