ABSTRACT:
An image forming apparatus which forms a toner image which is transferred onto a copy sheet includes a fixing unit having a heater for fixing the toner image onto the copy sheet at a predetermined fixing temperature. A cooling unit operates at a first cooling state for cooling the fixing unit. A mode selector is provided for setting a mode of the image forming apparatus to an energy saving mode in which heating operation by the heater is halted. A cooling controller suspends cooling operation of the cooling unit after a delay following a time when the image forming apparatus is set to the energy saving mode.
