Claims

[Claims for Utility Model Registration] (1) Fixing is carried out by transporting a sheet of paper on which an unfixed image is formed while being held between a first roller and a second roller that is in contact with the first roller. A fixing means, an opening/closing means integrally having a cover rotatable about a fulcrum to separate the first roller from the second roller when necessary and protecting the fixing means, and an entrance to the fixing means. In the image forming apparatus, the rotating body is partially attached to the cover, faces the surface of the paper on which the unfixed image is formed, and makes point contact with the paper, and the rotating body is partially attached to the cover, and the rotating body is in point contact with the paper. An image forming apparatus characterized in that a guide member located on a movement locus of the rotating body is provided with an escape portion that allows the rotating body to pass through. (2) The image forming apparatus according to claim 1, wherein the guide member provided with the relief portion is a conveyance guide provided along a conveyance belt that brings the paper to the entrance portion. (3) The image according to claim 1, wherein the guide member provided with the escape portion is a lower guide arranged vertically opposite to an upper guide formed on the cover. Forming device. (4) The rotating body is attached to the cover via a holder, and the holder further includes a guide that guides the paper conveyed toward the rotating body to a position lower than the height of the center of the rotating body. 2. The image forming apparatus according to claim 1, wherein a member is provided, and the relief portion is formed to allow passage of the guide member.
