ABSTRACT:
An image fixing rotatable member includes an elastic layer into which inorganic filler material is mixed; a bonding layer on the elastic layer, containing resin material; and a resin layer applied and sintered on the bonding layer. The elastic layer below the bonding layer has a heat conductivity higher than that of the resin material in the bonding layer and contains an inorganic filler having a heat conductivity higher than that of the resin material used in the bonding layer. Because of these specific features of the bonding layer and the elastic layer, the resin in the bonding layer functions as a thermal barrier during the sintering of the resin and therefore the heat transmitted to the rubber layer is not accumulated but is effectively dissipated as a result of the high conductivity of the inorganic filler.
