Abstract
According to one embodiment, a heating device includes a fixing belt configured to be rotated and a pressure roller configured to abut against the fixing belt and be driven to cause the fixing belt to rotate. A heater is configured to heat the fixing belt. A motor is configured to drive the pressure roller to rotate. A current sensor is configured to measure a driving current of the motor. A controller is configured to stop the heater based on the measured driving current.
