Abstract
A fixing unit fixing an image on a paper and an image-forming apparatus having the same are provided. The fixing unit includes a heat roller, pressure rollers, a bracket, springs, and a paper guide. The heat roller has a heat source therein and the pressure rollers face the heat roller to form fixing nips. The bracket rotatably supports the pressure rollers and is also adapted to pivot. The springs elastically pressurize the bracket to closely attach the pressure rollers on the heat roller and the paper guide guides a paper so that a paper jam may not occur between the pressure rollers.
