摘要：
A fixing device includes a tubular belt holder, a rotatable, flexible fuser belt, a heater, a fuser pad, a pressure member, and a reinforcing member. The fuser belt is looped for rotation around 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, and extends in an axial direction of the belt holder. The pressure member is disposed opposite the belt holder with the fuser belt interposed between the fuser pad and the pressure member. The reinforcing member is disposed inside the loop of the fuser belt to reinforce the fuser pad under pressure from the pressure member. The fuser pad includes an elongated base, multiple longitudinally spaced protrusions, a perforated, anti-friction cover, and a fastener.
