ABSTRACT:
When fixing images onto normal sheets of paper, the pressing force between a pressing roller and a thermal roller of a fixing unit is designated by the urging force of only a first spring. On the other hand, when fixing images onto thick sheets, the pressing force is designated by the urging force of the first spring and the urging force of a second spring, which operates against the urging force of the first spring.
