The fuser belt is looped around the belt holder to rotate in a circumferential direction of the belt holder. The heater is disposed adjacent to the belt holder to heat the belt holder. The fuser pad is accommodated in the belt holder inside the loop of the fuser belt. The pressure member is disposed opposite the belt holder with the fuser belt interposed between the fuser pad and the pressure member. The pressure member presses in a load direction against the fuser pad through the fuser belt to form a fixing nip therebetween. The belt holder includes, along a circumferential dimension thereof, an upstream, first circumferential portion, a downstream, second circumferential portion, and a midstream, third circumferential portion.

摘要： A fixing device includes a fixing rotator, a pressure rotator, a cleaner, a moving assembly, and a temperature detector. The fixing rotator heats and fixes a toner image onto a recording medium. The pressure rotator presses against the fixing rotator. The cleaner contacts and cleans a cleaning target, which includes one of the fixing rotator and the pressure rotator. The moving assembly moves the cleaner between a contact position where the cleaner contacts the cleaning target and a separate position where the cleaner is apart from the cleaning target. The temperature detector detects a temperature of one of the cleaner and the cleaning target. The moving assembly moves the cleaner from the contact position to the separate position or from the separate position to the contact position during rotation of the cleaning target, in a case in which the temperature detected is greater than a given value

摘要： A fixing device for fixing an unfixed image onto a recording medium includes a fixing belt, a nip forming member, an opposing rotary member, a heater, and a temperature detector. The fixing belt is formed into a loop to move endlessly and fix the unfixed image on the recording medium. The nip forming member is disposed inside the loop formed by the fixing belt. The opposing rotary member contacts the nip forming member via the fixing belt to form a nip portion therebetween while rotating. The heater heats the fixing belt at a place other than the nip portion. The temperature detector detects a temperature of the surface of the fixing belt. The temperature detector detects the temperature near a place of the fixing belt that easily deforms as the fixing belt is heated by the heater.
