Abstract
A fixing device includes a heater, a switching element, a zero-cross detecting portion, a controller, a power source, a driving portion. In a case that an amount of electric charge charged in the power source is predetermined value or more, the controller outputs a first signal to the driving portion so that a time in which a current is passed from the power source to the switching element is a first time. In a case that the amount of the electric charge is less than the predetermined value, the controller outputs a second signal to the driving portion so that the time in which the current is passed from the power source to the switching element is a second time shorter than the first time.
