Abstract
A fixing device includes: a sensor circuit portion which includes a plurality of series circuits of thermistors and capacitors and in which the capacitors differ from each other in capacitance; a signal circuit portion to which each sensor output voltage that is a voltage between the thermistor and the capacitor is input and which switches between output levels each time the sensor output voltage that exceeds a threshold value is increased; and a processing circuit that includes a output port to which the series circuits are connected so as to be parallel to each other and an input port and that recognizes a target temperature to be detected with each of the thermistors based on a rising time since the start of the voltage application to each of the series circuits until the output signal rises and a falling time until the output signal falls that are measured.
