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： An image forming apparatus includes a transfer unit, a fuser unit, a relative positioning mechanism, and a fine adjustment mechanism. The transfer unit has a transfer nip to transfer an image from an imaging surface to a recording sheet passing therethrough. The fuser unit has a fixing nip to fix the transferred image on the recording sheet passing therethrough. The relative positioning mechanism is configured to position the transfer unit and the fuser unit relative to each other by contacting a contact portion with a flange. The contact portion is formed on one of the transfer unit and the fuser unit. The flange is formed on the other of the transfer unit and the fuser unit. The fine adjustment mechanism is configured to align the transfer nip and the fusing nip relative to each other.
