A fusing device of an image forming apparatus which applies principles of leverage, and an image forming apparatus containing such a device. The fusing device includes a fusing unit having a heating roller (21) and a pressure roller (22) facing each other and which rotate together, a cover (24) which opens and closes the fusing unit, and a pressure and release unit (23), one end of which is rotatably fixed to a rotating shaft (26'), the pressure and release unit (23) containing a member (26) having a pressuring unit which pressures the pressure roller (22) towards the heating roller (21) when the cover (24) opens and shuts, and a pressured part (26a), which is farther from the rotating shaft (26') than the pressuring part (26b) and which receives pressure from the cover (24). |
