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.
Claims20
An image forming apparatus comprising:
- a voltage measuring device configured to measure an input voltage;
- a fixing device comprising a heater configured to heat a sheet;
- and
- a controller configured to determine a heating timing of the heater based on the voltage when the measured voltage becomes equal to or greater than a threshold value and to activate the heater at the determined heating timing,
- wherein, in response to the voltage measured by the voltage measuring device becoming equal to or greater than the threshold value, the controller is configured to execute a sheet printing process by performing a printing control in which an efficiency of a printing operation is reduced.
