Abstract
According to at least one embodiment, an image forming apparatus includes a voltage measuring device, a fixing device, and a controller. The voltage measuring device measures an input voltage. The fixing device includes a heater that heats a sheet. When the measured voltage becomes equal to or greater than a threshold value, the controller determines a heating timing of the heater based on the voltage and activates the heater at the determined heating timing.
