PROBLEM TO BE SOLVED: To improve separability of a recording medium from a heating means, without having to impose a large load on the recording medium by simplifying the configuration of a fixing device. SOLUTION: A pressing means of pressing the recording medium against a heat fixing roller as a heating member has a pressing member 21 and its holding member, a pressure spring pressing them against the recording medium, and a driven belt-like endless member, and a pad 21a as a portion of the pressing member 21 has its width-directional size made longer at a center part in the long-axis direction than at end parts (center part length L1> end part length L2). Consequently, the recording medium enters a nip part between the heating member and thereby pressing member from the center part of the recording medium to be conveyed, so that even if the recording member has wrinkles, the wrinkles move from the center part to an end part and can, as a result, reduce the occurrence of wrinkles.
