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.
