Abstract
A pressure fixing device for a recording medium comprises a pair of frames, a first roll rotatably supported by the frames, two pair of guide members attached individually to the frames to be movable at right angles to the axis of the first roll, second and third rolls disposed along the first roll so that both ends of the rolls are supported individually by the guide members for rotation, the recording medium being passed between the first and second rolls, and a mechanism for urging the second roll toward the first roll. The mechanism including a pair of compression coil springs extending along the axes of the rolls to apply an urging force in its extending direction, a pair of pressure levers rockable around an axis normal to the axes of the rolls and the moving direction of the guide members, the pressure levers receiving the urging force of the coil springs to urge the second roll toward the first roll. The urging force of the compression coil springs is controlled to adjust the pressure between the first and second rolls through the pressure lever and third roll.
