Abstract
A toner fixation film has an exothermic layer within which an eddy current is induced with application of a magnetic field and then heat is generated. The exothermic layer is a composite layer in which an exothermic part and resin part coexist. The toner fixation film can offer a sufficient heat generation necessary for toner fixation, and has enough flexiblity to permit curvature separation. A toner fixation apparatus comprises the toner fixation film and at least one coil for producing an alternating magnetic field for eddy current induction.
