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:0.001&#x2266;S&#x2266;0.13, and&#x2003;&#x2003;(1)85&#xd7;+3&#x2266;&#x2266;350&#xd7;+3&#x2003;&#x2003;(2)wherein S represents a sulfur content (mass %) and F represents an iron content (mass %).

Metal belt, fixing belt and heat fixing device

Objects of the present invention are to provide an endless metal belt superior in flexing resistance and durability, to provide a fixing belt using the endless metal belt, and to provide a heat fixing device with high durability and high reliability. The objects are achieved by the endless metal belt formed of a nickel alloy containing 5% by weight or more of an additional metallic element and having a half-value width of an X-ray diffraction peak in a range of 0.5 degrees to 2 degrees for each of a crystal plane and a crystal plane, and by using the same.
