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： A fixing device includes a substantially cylindrical metal member, a heater, an endless, flexible fixing member, a rotary pressing member, a stationary member, a first temperature detector, and a second temperature detector. The first temperature detector is disposed upstream from a nip in a rotation direction of the fixing member to detect a surface temperature of the fixing member. The second temperature detector is disposed downstream from the nip in a rotation direction of the pressing member to detect a surface temperature of the pressing member. When a difference between a surface temperature of the fixing member detected by the first temperature detector and a surface temperature of the pressing member detected by the second temperature detector after a predetermined time has elapsed since the first temperature detector detects the surface temperature of the fixing member is greater than a predetermined threshold, the heater stops heating the metal member.
