摘要： 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.

摘要： A fixing device for fixing an unfixed toner image on a recording medium includes a fixing member, a pressure member, a sheet guide, and a pressure adjusting mechanism. The fixing member heats the unfixed toner image on the recording medium. The pressure member is disposed opposite the fixing member and presses against the fixing member to define a fixing nip through which the recording medium bearing the unfixed toner image passes to fix the unfixed toner image onto the recording medium. The position of the fixing nip is changeable. The sheet guide disposed adjacent to the pressure member guides the recording medium to the fixing nip and moves in conjunction with movement of the pressure member. The pressure adjusting mechanism operatively connected to the pressure member adjusts an amount of engagement of the pressure member relative to the fixing member. An image forming apparatus includes the fixing device.
