Abstract

PURPOSE:To uniformize pressure distribution, by providing the first pressing roller for pressing an image supporting material, and the second pressing roller for pressing the material, differing from the first roller in surface moving speed and moving direction at their contact part in rotation. CONSTITUTION:Roller 4 is placed on roller 5 crossing it at an angle of theta, and roller 3 is further placed on roller 4 in parallel to this. Pressing arms 111, 112 are formed in one body with fixed block 21 of bearing block 2 and mobile block 22, respectively, and the force of spring 14 is applied to the arms 111, 112 by fixing it to them with pressing bolt 12, washer 13 for receiving spring 14, and a nut to excercise necessary force on an image supporting material between rollers 3, 4 using pin 10 as a support shaft, thus permitting rollers 3, 4 to be protected from abrasion caused by slip between rollers 6, 5, and pressure distribution to be made uniform by this protection, and further, failure, such as offset to be prevented.
