A fixing apparatus for fixing a toner image on a recording material, while conveying the recording material bearing the toner image, at a nip portion includes a tubular film, a heater configured to heat the film, and a pressure member configured to form the nip portion with the film, wherein the film has a property that a resistance value per unit area between an outer surface of the film and an inner surface of the film becomes 5×1011 (&OHgr;·cm2) or more when a voltage of 500 V or less is applied between the outer surface and the inner surface, and a resistance value per unit area between the outer surface and the inner surface becomes 5×109 (&OHgr;·cm2) or less when a voltage of 1000 V or more is applied between the outer surface and the inner surface. |
