<p>PROBLEM TO BE SOLVED: To prolong the life of a fixing roller by providing pressure force correcting means individually setting the pressure forces of a plurality of split rollers against other rollers constituting delivering rollers. SOLUTION: Springs 33 in the direction for returning the continuous paper 7 to the primary travel position are extended, the pressure forces of pressing rollers 30 in the returning direction are relatively increased, and the meandering of the continuous paper 7 is corrected. Since a plurality of pressing rollers 30 are split in the width direction of the continuous paper 7, the pressing force of the continuous paper 7 can be easily changed relatively in the width direction. A scuffing roller 29 may be divided into a plurality of rollers in the width direction of the continuous paper 7 like the pressing rollers 30. The toner image fixing function and the meandering correcting function for the continuous paper 7 can be shared by a fixing roller and delivering rollers. No biased load is applied to the fixing roller, toner can be uniformly fixed to the continuous paper 7, and the life of the fixing roller can be prolonged.</p> |
