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.

摘要： An image forming apparatus includes a fixing unit and a fixing process managing system. The fixing process managing system, including a mode switchover unit, controls a time mode and a temperature mode for heating a fixing member. In the time mode, the fixing unit is determined to be ready for a fixing process when a given time elapses after activation of the image forming apparatus. In the temperature mode, the fixing unit is determined to be ready for a fixing process when a temperature of the fixing member attains a given reference temperature after activation of the image forming apparatus. The mode switchover unit selects between the temperature mode and the time mode. The fixing process managing system selects the temperature mode instead of the time mode when a supply amount of electrical power to the fixing unit is determined to be below a required electrical power supply level.
