In an image forming apparatus according to an embodiment of the present invention, a fixing unit (16) demountably installed on a first frame (39) is provided with a heat roller (101), a pressure roller (102), and a lever (102a) which is pushed by a second frame ( 41) when the second frame is engaged with the first frame. The arrangement is such that the other side of the lever then pushes the pressure roller (102) at both ends of its shaft (102f) transversely towards the heat roller (101) for compression and heating of a sheet having a toner image thereon. When the second frame (41) is disengaged from the first frame (39) the pressure onto the lever (102a) is released and, consequently, the pressure roller (102) moves away from the heat roller (101) so that the pressure on the sheet is released for easy removal of the sheet therefrom. |
