Abstract
PURPOSE: To prevent the supporting body from being wrinkled and to perform the uniform pressure fixing treatment, by executing the pressure fixing treatment of an image of the supporting body to be turned in the regular direction by a pair of rollers and a crossing pressure roller, etc. whose diameter and second moment of area, etc. are fixed.
CONSTITUTION: The roller 7 of the first and second rollers 6, 7 by which the toner image supporting body is pressed and carried is made to closely contact the third roller 8 crossing with the roller 7. The roller 7 consists of hollow structure, its outside diameter is small comparing with that of the rollers 6, 8, and the second moment of area is set to 1/5 o less comparing with that of the roller 6. Therefore, pressure to the toner image supporting body becomes uniform. Furthermore, since the diameter of the rollers 6, 7 is selected so as to be comparatively small, and the distance between axes is small, the pressure through the roller 8 can be adjusted easily and exactly. Moreover, the toner image supporting body is carried by turning the side which is apt to be curled, in the direction of the roller 6, the toner supporting body is prevented from being wrinkled or curled, and the uniform pressure fixing treatment is executed.
