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. The fixing device has 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.

The heater heats the metal member. The fixing member is disposed rotatable around the metal member. An inner circumferential surface of the fixing member is heated by the metal member to heat and fix a toner image. The rotary pressing member is disposed opposite the metal member and pressed against an outer circumferential surface of the fixing member to form a nip between the rotary pressing member and the fixing member through which a recording medium bearing the toner image passes. The stationary member is disposed in pressure contact with the inner circumferential surface of the fixing member, and has an opposing face opposing the rotary pressing member and having a curvature smaller than a curvature of the rotary pressing member.

摘要： A fixing device includes a tubular, stationary metal pipe, a flexible fuser belt, a rotatable pressure member, a fuser pad, and a lubricant. The metal pipe is subjected to heating. The flexible fuser belt is looped for rotation around the metal pipe to transfer heat radially outward from the heated metal pipe. The rotatable pressure member extends opposite the metal pipe with the fuser belt interposed between the metal pipe and the pressure member. The fuser pad is held stationary inside the loop of the fuser belt to press against the pressure member through the fuser belt to form a fixing nip. The lubricant is of a given particle size and deposited between the metal pipe and the fuser belt. The surface of the metal pipe has a rough section which exhibits a surface roughness equal to or greater than the particle size of the lubricant.

摘要： In a fixing device, a nip formation member is provided inside a loop formed by a fixing member rotating in a predetermined direction of rotation. A 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 heat conduction member faces an inner circumferential surface of the fixing member to guide the fixing member sliding over the heat conduction member and to transmit heat to the fixing member. The heat conduction member includes a plurality of convex portions provided on an outer circumferential surface of the heat conduction member and contacting the inner circumferential surface of the fixing member.
