Abstract
A fixing apparatus for an image forming apparatus of the present invention includes: a rotatable heat roll; a heat-resistant elastic member fixedly disposed to form a nip section in contact with an outer circumferential surface of the heat roll, the heat-resistant elastic member being impregnated with a liquid release agent which is supplied to the nip section; and a porous fluororesin film formed by sintering a fluororesin powder for coating a surface of the heat-resistant elastic member coming in contact with the heat roll so that the release agent can be supplied by a predetermined amount while permeating through the film. The porous fluororesin film may include: a film formed by using metal fibers, glass fibers, or the like as a supporting member thereof, and a film formed by applying a gelled dimethyl silicone oil at least to a single surface of the film.
