PURPOSE: A heating roller for a fixing device is provided to secure durability and stability of combination of a gear cap with the body of the heating roller. CONSTITUTION: A heating roller for a fixing device includes a conductive cylindrical roller body(10), a resistant heat-radiator, an end cap, a gear cap(20), and the first and second combining members(30,40). The resistant heat-radiator is included in the roller body. The end cap and gear cap are respectively combined with both sides of the roller body and respectively have electrodes for supplying current to the resistant heat-radiator. The first combining member restricts the gear cap combined with the roller body from being escaped from the roller body in the axial direction of the roller body. The second combining member restricts the gear cap from racing.
