Abstract:
1. A fixing device comprising: a fixing unit configured to fix toner onto a recording medium transported in a determined transport direction, by using heat generated by a heat generator; a power controller configured to control supply of power for heating the fixing unit; a pressure applying unit configured to apply pressure to the recording medium in a nip part formed between the pressure applying unit and the fixing unit; and a timing controller configured to control starting or stopping of the power controller according to a determined time period with respect to an arrival time or a passage time of the recording medium, wherein the determined time period is determined in accordance with a time period from an output time point at which the timing controller outputs a signal for controlling the power controller to a time point at which the timing controller determines that a temperature of the heat generator has changed from a reference temperature by more than a determined value.
