Abstract
A device to prevent fire of a fusing belt having a heater positioned inside includes 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. The device also includes a heat absorption member adjacent to the other side of the fusing belt and to absorb latent heat from the fusing belt to lower the temperature of the fusing belt to prevent the fire.
