Abstract
In a fixing device, having a sheet portion and an inter-sheet portion, heats and fixes the toner image onto each of sheets by rotationally bringing the sheet portion into contact with each sheet. A heating unit heats the fixing unit. A sensing unit senses a temperature of the fixing unit. A control unit controls a duty ratio of on/off of the heating unit based on a sensing output of the sensing unit, determines whether the sensing unit is sensing the temperature of the sheet portion or the temperature of the inter-sheet portion in a rotation cycle, and controls the temperature of the heating unit by using the adjustment value corresponding to the sheet portion or the inter-sheet portion depending on a determination result.
