Fixing device controller, image forming apparatus, fixing device control method, and non-transitory computer-readable recording medium storing fixing device control program

摘要

A fixing device controller includes a plurality of voltage detectors to detect voltages of a plurality of power sources for supplying power to a plurality of heaters to heat a fixing member of a fixing device that fixes a toner image on a recording medium and a heater controller to execute duty control to turn on the plurality of heaters. The heater controller corrects a duty of at least one of the plurality of heaters based on the voltages detected by the plurality of voltage detectors and rated output values of the plurality of heaters.
