摘要： Disclosed is a method for controlling the temperature of a heat roller and an image forming apparatus based on the same. The image forming apparatus of the present invention includes: a heat roller for heating a printing paper having a toner image formed thereon to completely fuse the toner image to the printing paper; a heat lamp for heating the heat roller; and a controller for controlling the driving of the heat lamp, whereby the heat roller is maintained at a designated target temperature level during a pre-printing period. As such, it becomes possible to prevent a problem with the fusing process caused by low temperature of the heat roller during the pre-printing period for subsequent printing.

摘要： Disclosed is a method for controlling the operation of a fan in an electronic photo device including a developing device, a fan for keeping the temperature in the electronic photo device uniformly, and an output sensor for sensing output of a printed paper. According to the method, when a printable medium to be printed with print data is located between a transferring roller and an OPC drum of the developing device, the sort of the printable medium is determined. If it is determined that the printable medium is a first printable medium, the fan is stopped and a fixing process is performed. Otherwise, if it is determined that the printable medium is a second printable medium, the fixing step is performed under the condition that the fan is not stopped.
