Abstract
A method and apparatus for fuser cooling fan control is provided. An image forming apparatus so configured comprises a fixing unit, a cooling fan for cooling the fixing unit, a detecting sensor for measuring ambient temperature and humidity of the image forming apparatus, and a controller for recognizing ambient temperature and humidity change from the measurement provided by the detecting sensor. The controller controls operation of the cooling fan according to the temperature and humidity change detected. The controller delays operation of the cooling fan by an amount of time if the ambient temperature and/or humidity is below a reference temperature and humidity level.
