Patent ID: 8606164

Claim:
An image heating device comprising: a rotatable image heating member including an elastic layer and a surface layer in which a filler is dispersed; and a fixed pressing member which is contacted to a surface of said rotatable image heating member and forms a nip, between itself and said rotatable image heating member, in which a recording material for carrying an image is to be nip-conveyed, wherein the surface of said rotatable image heating member has a shape such that projections are distributed by the filler so that a coefficient of dynamic friction, μ(hot), of the surface of said rotatable image heating member when a surface temperature of said rotatable image heating member is a temperature during image heating and a coefficient of dynamic friction, μ(cold), of the surface of said rotatable image heating member when the surface temperature is 25° C. satisfy, μ(hot)<1.2×μ(cold).
