Abstract

Abstract PURPOSE:To prevent damage such as the wrinkling, folding, etc., of an end part of a film by setting relation condition of C<D, where C is the width of the film and D is the length of a nip part. CONSTITUTION:The width C of the film 21 and the length D of the nip formed by pressing a heating body 19 and a pressure roller 10 as a rotary body against each other across the film 21 are so set that C<D. The internal surface of the film 21 in the overall width area C contacts the surface of the heating body 19 in the length range and the film is conveyed by sliding on the surface of the heating body, so the film conveying force in the overall length area C in the film width direction is uniformed to evade film end part breakage trouble. Consequently, the film end part damage can be prevented and the device with stability and reliability is obtained.
