Abstract:
A fixing apparatus includes a fixing member for fixing an unfixed toner image on a sheet at a nip, a nip forming member for forming the nip cooperatively with the fixing member, a first heater for heating an external surface of the fixing member by contacting the external surface of the fixing member at a first position, and a second heater provided at a position upstream of the nip and downstream of the first position in a rotational direction of the fixing member, and for heating an external surface of the fixing member by contacting the external surface of the fixing member at a second position. The first heater has a thermal capacity larger than the second heater.
