Abstract
According to one embodiment, a fixing device includes a heating rotator to contact a medium, such as a sheet of paper, on which a toner image has been disposed. A heater is inside the heating rotator to heat the medium. A pressurizing rotator is configured to press against the heating rotator to form a nip through which the medium passes. A controller is configured to drive the heater to heat the heating rotator to a target temperature. The controller is configured to set the target temperature according to a length of a standby time between an end of a first image forming process to a start of a second image forming process after the first image forming process.
