ENDLESS BELT, FIXING DEVICE, AND IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To provide an endless belt that suppresses displacement of the position of a toner image.SOLUTION: There is provided an endless belt 60 that includes an endless belt base material 62 and a meandering suppression member 64 that is arranged in the circumferential direction at least at one end in the width direction of the belt base material, where a value obtained by subtracting the coefficient of linear thermal expansion of the meandering suppression member from the coefficient of linear thermal expansion of the belt base material is -1×10/°C or more and 20×10/°C or less, and the tensile stress at an elongation of 300% of the meandering suppression member is 5 MPa or more.SELECTED DRAWING: Figure 1 【課題】トナー画像の位置ずれを抑制する無端ベルトを提供する。【解決手段】無端状のベルト基材６２と、前記ベルト基材の幅方向の少なくとも一端部において周方向に配置された帯状の蛇行抑制部材６４と、を有し、前記ベルト基材の線熱膨張率から前記蛇行抑制部材の線熱膨張率を引いた値が−１×１０−５／℃以上２０×１０−５／℃以下であり、且つ、前記蛇行抑制部材の伸び３００％時の引張応力が５ＭＰａ以上である無端ベルト６０。【選択図】図１
