摘要： In a fixing device, a heating element is extended along a fixing member at a location other than a nip on an inner circumferential surface side of the fixing member to generate heat. The fixing member contacts the heating element either indirectly via a gap of a prescribed size or directly contacts the heating element by with a prescribed pressure when the fixing member is rotating, and continuously separates from the heating element by a prescribed distance greater than the size of the gap when the fixing member stops rotating.

摘要： A fixing device includes a hollow, generally cylindrical open-sided stationary heat roll, a flexible fuser belt, a fuser pad, a rotatable pressure member, and a roll shape retainer. The heat roll is configured to heat an outer circumference thereof, and defines an elongated longitudinal side opening in one side thereof. The fuser belt is looped for rotation around the heat roll to transfer heat radially outward from the roll circumference. The fuser pad is held substantially stationary along the roll opening outward from the roll hollow and inward from the loop of the fuser belt. The pressure member is pressed against the fuser pad through the fuser belt to form a fixing nip. The roll shape retainer is disposed on the roll opening to retain the generally cylindrical shape of the heat roll.
