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.
