PROBLEM TO BE SOLVED: To provide a transfer fixing device using transfer fixing technique to obtain a fixing effect by pressure without delaying in time by heating a toner image transferred to a transfer fixing member before bringing it into contact with a recording medium and bringing the toner image into contact with the recording medium in a melted state, thereby transferring and fixing it. SOLUTION: The transfer fixing device is equipped with: the transfer fixing member 1 rotating while holding the transferred toner image on its peripheral surface; a heating means 14 heating the toner image on the transfer fixing member to the melted state; and a pressure member 2 coming into contact with the peripheral surface of the transfer fixing member and forming a nip part N, and transfers and fixes the toner image on the recording medium while pressuring it in a process where the recording medium is made to pass through the nip part. It is equipped with a pressing member 31 arranged to be opposed to the pressure member through the transfer fixing member and forming a nip part facing to the pressure member side with the pressure member. In the nip part, nip part pressure on an exit side of the recording medium is set to be smaller than that on an entrance side thereof. COPYRIGHT: (C)2008,JPO&INPIT
