Zusammenfassung:In one embodiment, an image forming apparatus includes a fixing device with a heating element to heat a sheet. A controller is configured to control electric power supplied to the heating element based on a prior use metric. The controller reduces the electric power supplied to the heating element during a startup period if an electric power level supplied from a power supply is equal to or greater than a threshold value and the prior use metric is equal to or greater than a reference value.
