Abstract
A fixing device includes a first rotator, a second rotator, a heater, a separator, and a resistor. The second rotator is in contact with an outer circumferential surface of the first rotator to form a nip through which a recording medium bearing an unfixed image passes. The heater includes a heat generator and heats the first rotator. The separator is in contact with an outer circumferential surface of the first rotator and separates the recording medium passing through the nip from the first rotator. The resistor couples the second rotator and the separator to the ground.
