Abstract
A heating device includes a belt, a heater that is in contact with an inner surface of the belt and divided into heater blocks in a width direction thereof, a pressing member that presses a sheet against the belt, a temperature sensor disposed on each of a number of the heater blocks that is at least one-half of the total number thereof, and a processor configured to select one or more of the heater blocks based on a width of the sheet, and select one or more temperature sensors disposed on one or more of the selected heater blocks having the non-paper passing region and control electric power supplied to said one or more of the selected heater blocks to protect against an excessive temperature rise in the non-paper passing region based on temperatures detected by the temperature sensors.
