    • An object of the present invention is to provide an image heating apparatus having a flexible sleeve of an excellent durability. To this end, an image heating apparatus according to the present invention includes: a flexible sleeve; a driving roller contacting an external periphery surface of the sleeve and serving to rotate the sleeve; a sliding member contacting an internal periphery surface of the sleeve to form a nip portion in cooperation with the driving roller; and a restricting member for restricting a movement of the sleeve in a generatrix direction of the sleeve, wherein, within an edge face of the sleeve in a mounted state on the apparatus, equally bisected by an imaginary plane substantially parallel to a nip plane of the nip portion into a first area closer to the nip portion and a second area farther from the nip portion, the restricting member executes a restricting action only on the second area.
    • 本发明的目的是提供一种具有优异耐久性的柔性套筒的图像加热装置。 为此,根据本发明的图像加热装置包括:柔性套筒; 驱动辊与套筒的外周表面接触并用于使套筒旋转; 滑动构件与所述套筒的内周面接触以与所述驱动辊协作形成压合部; 以及限制构件,用于限制套筒在套筒的母线方向上的运动,其中,在装置的安装状态下在套筒的边缘面内,被平均于基本上平行于 夹持部分进入更靠近夹持部分的第一区域和离咬合部分更远的第二区域,限制构件仅在第二区域上执行限制动作。
