    摘要： A fusing device includes a rotatable pressing roller, a fusing belt to rotate by a rotational force transmitted from the rotatable pressing roller, a nip forming member to contact an inner surface of the fusing belt to form a nip on a contact area between the rotatable pressing roller and the fusing belt, a heating member formed in approximately an internal central portion of the fusing belt to heat the nip forming member and the fusing belt, an inner support member formed within the fusing belt to press a nip part of the nip forming member toward the rotatable pressing roller, and an outer support member formed outside the fusing belt, and both ends of the outer support member being engaged with the inner support member to thereby reinforce the strength of the inner support member and form a path for radiation heat to disperse. The support unit includes an inner support member placed within the belt unit, and an outer support member placed outside the belt unit, both ends of the outer support member being engaged with the inner support member to reinforce the strength of the inner support member and to form a path for a radiation heat to disperse.
