摘要： An embodiment of the invention includes a fixing device of an image forming apparatus. The fixing device may include a first pressure applying roller, a second pressure applying roller which is pressed onto the first pressure applying roller, and a fixing belt which is entrained about the first pressure applying roller and is pressed onto the first pressure applying roller by the second pressure applying roller. When a transfer material carrying an unfixed image is inserted between the second pressure applying roller and the fixing belt, the unfixed image may be brought into contact with the fixing belt so that the unfixed image is heated and fixed on the transfer material. A frictional coefficient between the fixing belt and the first pressure applying roller may be set to be less than a frictional coefficient between the fixing belt and the transfer material.
