Abstract
PURPOSE: To eliminate uneven fixing by specifying the pressing means which pressure contacts a movable roller to a stationary roller.
CONSTITUTION: The pressing means is constituted by connecting the both end shafts 4 of the movable roller 3 loosely fitting in the oblong holes 6 of side plates to the output shaft 9 of a constant torque generator 8 by means of steel wires 7. If with this arrangement the torque in the arrow A direction is applied to the constant torque generator 8 consisting of a DC motor or the like controlled by constant current, then the steel wires 7 are pulled downward by fixed force P and the movable roller 3 is detachably pressure-contacted to the stationary roller 1 by the force P. Hence, even if the paper thickness t of the coyping paper S changes, all it occurs is a change in the angle θ of the output shaft 9 and the fixing pressure P is maintained constant, thus always constant fixing pressure is generated irrespective of the paper thickness t and the occurrence of uneven fixing prevented.
