摘要： A fixing device includes a stationary at least partially tubular thermal member, a flexible fuser belt, a fuser pad, and a rotatable pressure member. The thermal member has a tubular portion thereof extending in an axial direction and defining a closed axial cross-section. A circumference of the thermal member is subjected to heating. The fuser belt is looped for rotation around the thermal member. An inner circumference of the fuser belt at least partially faces the thermal member. The fuser pad is held stationary inside the loop of the fuser belt. The pressure member extends opposite the thermal member in the axial direction with the fuser belt interposed between the fuser pad and the pressure member. The fuser pad is pressed against the pressure member through the fuser belt to form a fixing nip. The thermal member is spaced apart from the fuser pad.

摘要： A fixing device includes a tubular, stationary metal pipe, a heater, a flexible fuser belt, a rotatable pressure member, a fuser pad, and a tubular pipe cover. The heater is disposed adjacent to the metal pipe to heat a circumference thereof. The metal pipe has multiple through-holes provided at least at a circumferential perforated section thereof. The flexible fuser belt is looped for rotation around the metal pipe to transfer heat radially outward from the heated circumference of the 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, accommodated within the metal pipe, held stationary inside the loop of the fuser belt, presses against the pressure member through the fuser belt to form a fixing nip. The tubular pipe cover is fitted around the metal pipe.
