Condenser type fixing and image forming apparatuses

A fixing apparatus comprising:

• a first heat generating member configured to generate heat when AC power is supplied by a commercial power source;
• an electrical condenser charged by the commercial power source;
• a second heat generating member configured to generate heat when the electrical condenser supplies DC power;
• a fixing member heated by the first and second heat generating members and configured to heat and fix an image onto a recording medium;
• a first power supply circuit configured to convey AC power from the commercial power source to the first heat generating member;
• a second power supply circuit configured to convey DC power from the electrical condenser to the second heat generating member;
• and
• a first cutting off device configured to cut off the first power supply circuit when the temperature switch is operated.
