An image heating device includes 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 the rotatable image heating member and forms a nip, between itself and the rotatable image heating member, in which a recording material for carrying an image is to be nip-conveyed. The surface of the rotatable image heating member has a shape such that projections are distributed by the filler so that a coefficient of dynamic friction mu(hot) relative to said fixed pressing member when a surface temperature of the rotatable image heating member is a temperature during image heating and a coefficient of dynamic friction mu(cold) relative to the fixed pressing member when the surface temperature is a normal temperature satisfy, mu(hot)<1.2�mu(cold). |
