Fixing apparatus and image forming apparatus having the same

A fixing apparatus configured to fix a toner image on a recording medium, the fixing apparatus comprising:

• a fixing unit configured to fix the toner image on the recording medium by heat;
• a cooling unit configured to cool a heating area of the fixing unit;
• and
• a control unit configured to start a predetermined heating of the heating area of the fixing unit while cooling the heating area of the fixing unit by the cooling unit after the heating area of the fixing unit is cooled by the cooling unit.

A fixing apparatus configured to fix a toner image on a recording medium, the fixing apparatus comprising:

• a fixing unit configured to fix the toner image on the recording medium by heat;
• a cooling unit configured to cool a heating area of the fixing unit;
• and
• a control unit configured to start a predetermined heating of the heating area of the fixing unit while cooling the heating area of the fixing unit by the cooling unit in a case where the control unit determines that a temperature of the heating area of the fixing unit has dropped to a predetermined temperature.

A fixing apparatus configured to fix a toner image on a recording medium, the fixing apparatus comprising:

• a fixing unit configured to fix the toner image on the recording medium by heat, the fixing unit heating the recording medium when the recording medium is conveyed through a heating area of the fixing unit;
• a cooling unit configured to cool the heating area of the fixing unit;
• and
• a control unit configured to perform a predetermined heating of the heating area of the fixing unit while cooling the heating area of the fixing unit by the cooling unit, the control unit preventing the fixing unit from performing the predetermined heating of the heating area of the fixing unit while cooling the heating area of the fixing unit by the cooling unit when the recording medium is conveyed through the heating area of the fixing unit.
