Abstract
An image forming apparatus that forms a toner image on a recording medium includes an image forming unit that forms an unfixed toner image on a recording medium; a fixing unit that heats the recording medium bearing the unfixed toner image and fixes the unfixed toner image onto the recording medium at a nip portion; a heating member and a pressurizing member that touches the heating member and forms the nip portion therebetween; a first blower that blows air to a non-sheet-passing area of a small-size recording medium in the heating member; and a second blower that blows air to a non-sheet-passing area of a small-size recording medium in the pressurizing member. Upon the temperature of the non-sheet-passing area of the heating member exceeding a threshold temperature, the first blower blows without the second blower blowing, then the two blowers start blowing together.
