Fixing belt and an image heat fixing assembly using the same

摘要

In a fixing belt (10) having at least a release layer (3) and a metal layer (1) formed of electroformed nickel, the electroformed nickel has, in its crystal texture, crystallites having an average size of 0.05 mu m or more and 0.2 mu m or less. This fixing belt has high durability, and an image heat fixing assembly using this fixing belt has high durability and high reliability and realizes low-energy heating by utilizing a heating element with a small heat capacity.
