ABSTRACT:
Provided are a metal belt which is improved in wear resistance, thermal conductivity, thin wall designs, heat resistance and flexibility, a fixing belt in which this metal belt is used, and a high durability and high reliability heat fixing device which has this fixing belt. This metal belt is made of a nickel-iron alloy manufactured by an electroforming process, and the nickel-iron alloy satisfies relationships expressed by the following equations:in-line-formulae description="In-line Formulae" end="lead"?0.001≦S≦0.13, and  (1)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?85×S+3≦F≦350×S+3  (2)in-line-formulae description="In-line Formulae" end="tail"?wherein S represents a sulfur content (mass %) and F represents an iron content (mass %).
