    Abstract: An image forming apparatus includes an adjustment unit that adjusts an image transfer position of the sheet of paper along a main scanning direction that is orthogonal to a transporting direction of the sheet of paper, a fixing unit that fixes on the sheet of paper an toner image using fixing rollers and performs a fluctuation of the fixing roller to the main scanning direction, a detection unit that detects whether or not the fixing rollers of the fixing unit nip the sheet of paper, and a controller. The controller controls the fixing unit to perform the fluctuation of the fixing rollers when determining that the fixing rollers of the fixing unit do not nip the sheet of paper based on a detection result of the detection unit.
