Abstract
A heating device includes a belt, a heater, a first temperature sensor, a second temperature sensor, a circuitry, and a heat-source controller. The heater includes a heat source to heat the belt. The first temperature sensor is disposed at a position facing the heater via the belt and separated from the belt to detect a first temperature of the belt. The second temperature sensor is disposed at a position directly facing the heater and separated from the heater, to detect a second temperature of the heater. The circuitry corrects the first temperature detected by the first temperature sensor based on the second temperature detected by the second temperature sensor. The heat-source controller controls the heat source based on the first temperature corrected by the circuitry.
Claims6
A heating device comprising:
- a belt;
- a heater including a heat source to heat the belt;
- a first temperature sensor, at a position facing the heater via the belt and separated from the belt, to detect a first temperature of the belt;
