Abstract
A fixing device wherein a toner image on a paper sheet passing either of two paper paths can be fixed by means of a single heat roll. The fixing device comprises a single heat roll, a pair of pressure rolls for contacting under pressure with the heat roll, and a pair of paper passing means for individually passing a paper sheet to a pair of contact positions at which the heat roll normally contacts with the pressure rolls. By selectively passing a paper sheet having a toner image thereon to one of the contact positions with the toner image opposed to the heat roll, the toner image is fixed to the paper sheet by heat and mechanical pressure of the heat roll and the pressure rolls.
