摘要： A fixing device includes a hollow, stationary metal roller, a flexible fuser belt, a rotatable pressure member, a fuser pad, a reinforcing member, and a heating assembly. The metal roller has an outer circumference thereof subjected to heating. The flexible fuser belt is looped for rotation around the metal roller to transfer heat radially outward from the heated metal roller. The fuser pad is held stationary inside the loop of the fuser belt to press against the pressure member through the fuser belt to form a fixing nip. The reinforcing member is disposed stationary within the roller interior. The heating assembly is disposed stationary within the roller interior to heat the metal roller from inside, and includes a first heater and a second heater. The first and second heaters are arranged in juxtaposition with each other along the inner circumference of the metal roller.

摘要： A fixing device includes a tubular belt holder, a rotatable flexible fuser belt, a contact member, a pressure member, and a heater. The tubular belt holder extends in an axial direction thereof. The fuser belt is looped into a generally cylindrical configuration around the belt holder. The tubular belt holder retains the fuser belt in shape as the belt rotates in a circumferential direction. The contact member and pressure member extend in the axial direction. The pressure member presses against the contact member through the fuser belt to form a fixing nip. The heater is disposed to heat a predetermined circumferential portion of the fuser belt. The belt holder includes a first circumferential section and a second circumferential section. The first circumferential section faces the heated portion. The second circumferential section faces upstream from the heated portion in the circumferential direction.

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.
