ABSTRACT:
A fusing device (23) has heat reflectors (238) and (239) positioned in consideration of the fact that convective heat loss from respective outer surfaces of the heat reflectors (238) and (239) depends on orientation of the outer surfaces. More specifically, each of the heat reflectors (238) and (239) are positioned so as to have a convective heat transfer coefficient η of up to 0.9. The convective heat transfer coefficient η is given by the following expression:in-line-formulae description="In-line Formulae" end="lead"?η=(Su+0.77Sh+0.54Sd)/(Su+Sh+Sd),in-line-formulae description="In-line Formulae" end="tail"?were Su is a projected area of an outer surface of each of the heat reflectors on an upper horizontal plane, Sh is a projected area of the same on a vertical plane, and Sd is a projected area of the same on a lower horizontal plane.
