An image forming apparatus is provided to enable a print medium passed through the first pressing roller to enter between a heating roller and the second pressing roller, thereby preventing jam between the first pressing roller and the second pressing roller and preventing a defective image due to a touch of the second pressing roller. A fusing device includes a heating roller(110) having a heater(111), the first pressing roller(120) in which the first fusing nip(N1) is formed between the heating roller and the first pressing roller while the first pressing roller is tightly contacted with the heating roller, the second pressing roller(130) arranged in the lower side of the first pressing roller with regard to a transfer direction of a sheet, and a pressing device(160) for pressing the first and second pressing rollers to the heating roller. The pressing device includes supporting members(161,162) rotatably supporting shafts(121,131) of respective pressing rollers and elastic members(163,164) elastically pressing the supporting members to the respective pressing rollers to the heating roller. |
