PROBLEM TO BE SOLVED: To provide a heat fixing roller for an image forming device having excellent paper feeding properties without generating charges on the heat fixing roller 2 when an image carrying body 4 passes the fixing device 1 even in a high humidity environment. SOLUTION: In the heat fixing roller consisting of a metal core 8 and a plurality of elastic layers 9 made of different kinds of materials on the core, the outermost layer 93 of the plurality of elastic layers consists of an elastic material having <=1×1016Ωsurface resistivity and <=3% residual elongation when stretched by 50% by applying stress and then released from the stress.
