Fixing apparatus

A fixing apparatus for fixing a toner image on a recording material, the fixing apparatus comprising:

• a cylindrical film;
• a heater configured to make contact with the film, the heater including a substrate and a heat generation resistor formed on the substrate;
• and
• a heat conduction member configured to make contact with a surface of the heater opposite to a surface thereof being in contact with the film, the heat conduction member having a higher thermal conductivity than that of the substrate, and being divided into a plurality of parts in a generatrix direction of the film,
• wherein the toner image formed on the recording material is fixed on the recording material by using heat of the film, and
• wherein one of the parts obtained by dividing the heat conduction member is configured to make contact with the heater continuously from a center of a heat generation region of the heater in the generatrix direction to an end thereof.
