    • A fixing device to fix a toner image on a sheet includes a flexible endless belt that rotates in a predetermined direction, an inner circumferential surface of which includes a fluorine-containing surface layer, a rotary member that contacts an outer circumferential surface of the belt, a fixed member fixed inside the belt to press against the rotary member via the belt, forming a nip portion therebetween, a lubricant applied between the belt and the fixed member, and a heat source to heat at least one of the belt and the rotary member. A surface of the fixed member that slidingly contacts the inner circumferential surface of the belt includes a fluorine-containing surface layer. One of the fluorine-containing surface layers is porous, and at least one of the fluorine-containing surface layers has a surface energy greater than a surface tension of the lubricant.

    • A fixing device and image-forming apparatus, which provide required glossiness and paper adaptability, and, in addition, feature good operability and excellent durability while achieving optimal pressure-applying force for a variety of requirements, having: a pressure-applying lever; a pressure-releasing lever; a locking member, the one end of which is rotationally attached to the pressure-releasing lever; and an elastic member, which pulls the locking member in a locking direction. The configuration is such that the rotation of the pressure-releasing lever displaces the location of the locking member, thereby enabling switching between a pressure-applying position, in which a fixing member presses against another fixing member, and a pressure-releasing position, in which the one fixing member moves away from the other fixing member, and in the pressure-applying position, the pressure-applying lever and the locking member, which are fastened together at one end of the pressure-applying lever opposite a rotation central shaft, are pulled in a locking direction by the elastic member, and the gripping pressure on a piece of paper is varied by the pair of fixing members.
    • 提供所需的光泽度和纸张适应性的定影装置和图像形成装置,另外,具有良好的可操作性和优异的耐久性,同时为各种要求实现最佳的施加压力,具有:施压杆; 压力释放杆; 锁定构件,其一端旋转地附接到压力释放杆; 以及将锁定构件沿锁定方向拉动的弹性构件。 该配置使得释压杆的旋转移动锁定构件的位置,从而能够在固定构件压靠另一固定构件的压力施加位置与压力释放位置之间切换, 一个固定构件从另一个固定构件移动,并且在施压位置,压力施加杆和锁定构件在压力施加杆的与旋转中心轴相对的一端处紧固在一起, 通过弹性构件沿锁定方向被拉动,并且一张纸上的夹持压力由一对固定构件变化。
