Abstract:
A fixing device includes a tubular belt holder, a rotatable flexible fuser belt, a contact member, a pressure member, and a heater. The belt holder extends in an axial direction thereof. The fuser belt is looped around the belt holder extending in the axial direction. The contact member has a central axis thereof extending in the axial direction, accommodated in the belt holder. The pressure member has a central axis thereof extending in the axial direction, disposed opposite the belt holder with the fuser belt interposed between the contact member and the pressure member. The pressure member presses against the contact member through the fuser belt to form a fixing nip. The heater is disposed adjacent to the belt holder to heat a circumferential portion of the fuser belt. The belt holder includes a generally semi-cylindrical section to face the heated circumferential portion of the fuser belt.
