Summary:PROBLEM TO BE SOLVED: To provide a fixing belt having excellent bending resistance and wear resistance.SOLUTION: A fixing belt comprises: a belt base material 110A containing a polyimide resin; and a surface layer 110B which is fused to an outer circumferential surface of the belt base material 110A, contains an inert fluororesin, and has an innermost layer 110B1 forming a fusion surface with the belt base material 110A and an outermost layer 110B2 forming an outermost surface. A melt float rate (MFR) of the outermost layer 110B2 is smaller than the melt float rate (MFR) of the innermost layer 110B1. 【課題】耐屈曲性及び耐摩耗性に優れた定着ベルトを提供すること【解決手段】ポリイミド樹脂を含むベルト基材１１０Ａと、ベルト基材１１０Ａの外周面に融着して設けられ、不活性のフッ素樹脂を含む表面層１１０Ｂであって、ベルト基材１１０Ａとの融着面を構成する最内層１１０Ｂ１。及び、最外面を構成し、メルトフローレート（ＭＦＲ）が前記最内層のメルトフローレート（ＭＦＲ）よりも小さい最外層１１０Ｂ２を有する表面層１１０Ｂと、を備える定着ベルトである。【選択図】図１
