Summary:PROBLEM TO BE SOLVED: To satisfy flexibility by using a crystalline thermoplastic resin that can be manufactured at a low price, and reduce wrinkles on a sheet caused by contraction of the outer diameter of a fixing belt.SOLUTION: A fixing belt is mounted in a fixing device that heat-welds a toner image to a sheet. The fixing belt is an endless fixing belt having a layer containing a crystalline thermoplastic resin, and the crystalline thermoplastic resin has a crystallinity of 81% or more of the maximum saturation crystallinity of the crystalline thermoplastic resin.SELECTED DRAWING: Figure 1 【課題】安価に製造可能な結晶性熱可塑性樹脂を用い、耐屈曲性を満足すると同時に定着ベルトの外径収縮起因の用紙シワ抑制を目的とする。【解決手段】トナー像を用紙に熱溶着する定着装置に搭載する定着ベルトにおいて、前記定着ベルトは結晶性熱可塑性樹脂を含む層を有し、結晶性熱可塑性樹脂の結晶化度が結晶性熱可塑性樹脂の最大飽和結晶化度の８１％以上であることを特徴とする無端状の定着ベルト。【選択図】図１
