Abstract
A fixing device of the belt system is provided in which slippage of a heating belt is prevented from occurring so that a recording member is stably transported, and the inner face of an end portion of the heating belt is prevented from being damaged. In a fixing device, an endless heating belt 34 is supported by a driving roller 31 and a heating roller 33, a pressure roller is pressingly contacted with an outer peripheral portion of the belt so as to form a nip portion, and an unfixed image on a recording medium transported to the nip portion is fixed to the recording medium. The axial lengths L2 of the driving roller 31 and the heating roller 33 are set to be shorter than the width L1 of the belt 34, and the axial length L3 of an oil applying roller 51 which abuts against the outer peripheral portion of the belt 34 to apply oil thereto is set to be shorter than the axial lengths L2 of the driving roller 31 and the heating roller 33.
