摘要： A fixing device includes a fixing member, a nip formation member, a pressing member, and a low-friction sheet. The nip formation member is provided inside a loop formed by the fixing member rotating in a predetermined direction of rotation. The pressing member is pressed against the nip formation member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The fixing member and the pressing member rotate and convey the recording medium bearing the toner image through the nip. The low-friction sheet, over which the fixing member slides, covers the nip formation member. The nip formation member includes a first sandwiching member covered by the low-friction sheet, and a second sandwiching member sandwiching the low-friction sheet together with the first sandwiching member.

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 nip formation member includes a base, a high thermal conduction member, and a securing member. The high thermal conduction member has a thermal conductivity greater than a thermal conductivity of the base. The securing member is independent from the base and the high thermal conduction member. The securing member is configured to restrict movement of the base relative to the high thermal conduction member.
