Abstract
PURPOSE: To evenly apply load over the entire surface of copying paper and improve fixing characteristic by evenly pressure-contacting pressure rollers which have a diameter larger than that of fixing rollers and whose diameter in the central part is larger than that of the end part, to a pair of ifxing rollers.
CONSTITUTION: Pressure rollers 6, 7 from above and pressure roller 8, 9 from below are formed by rigid rollers composed of iron or metal or elastic rollers having elastic rubber on the surface which have a diameter larger than the diameter of a pair of fixing rollers 4, t constituted by rigid rollers composed or metal such as iron, are provided in an apparatus of performing fixing of toner images. Here, the diameter of the pressure rollers 6 thru 9 are made larger than the diameter of the fixing rollers 4, 5 and the diameter of their central part is made larger than the diameter of their end parts to constitute these rollers so that when these rollers are pressure-contacted to the fixing rollers 4, 5 an even load is applied between both rollers. Thereby, an even load may be applied over the entire surface at the time of fixing.
