Abstract
PURPOSE: To make it possible to apply a uniform high load to a toner image support by arranging both two pressure rollers having a larger diameter and a fixing roller such they are not in parallel with each other byt satisfy a preset condition.
CONSTITUTION: The diameter of pressure rollers 5 and 6 for pressing a fixing roller 4 is made larger than that of the latter roller. These rollers 4 to 6 are arranged such that their centers a, b and c in any cross-section are lcoated on a straight line passing through the contact portion Q of the rollers 4 and 6 but not in parallel. With this arrangement, the contact point Q of the intersecting rollers 4 and 6 for thermally fixing a toner image support S forms a straight line H in parallel with the axial line of the rollers 4 and 6. As a result, the load to be applied to the toner image carrier S is uniformalized by straightening the axial centers of the rollers 4 and 6, and the nip angle α between the rollers 4 and 6 for the carrier S through the contact line H is so reduced that a high load per unit area can be applied to the carrier S, thus ensuring the satisfactory fixing operation
