    • In a heat roll fixing unit, adapted to be positioned in a printer employing an electrophotographic system for forming an image on a continuous-sheet to be fed in the printer, a pair of rollers is provided that are arranged to be brought into and out of contact with each other for pressurizing the continuous-sheet to fix the image thereon. One of the pair of rollers is a heat roller that is heated by a predetermined heating member. The heat roll fixing unit further comprises a sheet separation mechanism located at the downstream side of the pair of rollers and arranged to be operable when the pair of rollers is brought out of contact with each other for separating the continuous-sheet from the heat roller. Thus, the continuous-sheet can be prevented from remaining in contact with the roller after the fixing operation in the heat roll fixing unit. It thus becomes possible to avoid jamming of the continuous-sheet.
