Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 薄肉の加熱媒体でも通紙モードに拘らず熱分 布を効率良く制御でき、加熱媒体の非通紙領域における 温度上昇を抑制し得る定着装置を提供する。 【解決手段】 金属スリーブ11と誘導コイル18との 間に、誘導コイル18から金属スリーブ11へ届く磁束 の一部を遮蔽する磁束遮蔽手段31を配置し、該磁束遮 蔽手段31の位置を、金属スリーブ11における通紙範 囲に応じて、変位手段40により変化させることによ り、通紙する記録材14のサイズの種類によらず昇温さ れる金属スリーブ11の熱分布をコントロール可能とし た。 [PROBLEMS] To provide a fixing device capable of efficiently controlling heat distribution even in a thin-walled heating medium regardless of a paper-passing mode and suppressing a temperature rise in a non-paper-passing area of the heating medium. SOLUTION: A magnetic flux shielding means 31 is arranged between a metal sleeve 11 and an induction coil 18 for shielding a part of a magnetic flux reaching from the induction coil 18 to the metal sleeve 11, and the position of the magnetic flux shielding means 31 is changed to a metal. The heat distribution of the metal sleeve 11 whose temperature is raised can be controlled irrespective of the type of the size of the recording material 14 to be passed by changing the displacement by the displacement means 40 according to the paper passing range in the sleeve 11.
