A fusing apparatus of an electrophotographic image forming apparatus includes an internal pipe having a tubular body portion and end portions integrally formed with the body portion at both ends of the body portion, a heat-generating portion installed to wrap the body portion to be in close contact with the body portion without a gap and to generate heat, and a fusing roller installed to wrap the heat-generating portion. The fusing apparatus provides a perfect contact between the heat-generating portion and the internal pipe, thereby maintaining an entire surface of the fusing roller at a uniform temperature without a temperature deviation. Therefore, an optimal efficiency in fixing a toner image on printer paper can be achieved.
