Abstract

PURPOSE:To prevent the occurrence of lines, etc. to the recording paper having different levels of thickness, by providing a mechanism to expand and contract a spring which is used for setting the load between the press-contact rollers and expanding/contracting the spring according to the strength of the press-contact force during the fixing to always keep the press-contact force at a constant level. CONSTITUTION:An inter-roll load spring 10 is provided under a backup roll guide piece 9 and pressed by an inter-roll load setting screw 11. A worm wheel 12 is fixed to the screw 11, and a worm 13 gears into the wheel 12. Then a press-contact screw feed motor 14 is attached to the edge of the worm 13.
