PROBLEM TO BE SOLVED: To simultaneously achieve reduction in running cost by reduction in toner consumption and higher image quality of a formed image in an electrophotographic image forming apparatus without making the particle diameter of toner extremely small. SOLUTION: In the electrophotographic image forming apparatus 45 comprising a toner image forming means 2, an intermediate transfer means 3 and a transfer fixing means 4, a toner image T secondarily transferred from an intermediate transfer belt 20 to a transfer fixing roller 30 is heated and formed into a film with a heating means 31 set within the transfer fixing roller 30, and the surface temperature of the transfer fixing roller 30 is kept at a value suitable for film formation of the toner image T with a temperature detecting means 32 set near a surface of the transfer fixing roller 30.
