Abstract:
1. A fixing device for forming a lenticular lens structure when using a light-transmissive recording medium, comprising: a fixing member for fusing an unfixed toner image on the recording medium and fixing the unfixed toner image onto the recording medium; a pressing member for conveying the recording medium while pressing the recording medium against the fixing member; a resin layer forming portion disposed in close proximity to the pressing member for forming a transparent resin layer by ejecting and applying a light-transmissive resin material on the surface of the pressing member; and a controller for controlling the operation of the resin layer forming portion, wherein the fixing member and the pressing member being put in pressure contact with each other to form a fixing nip portion so that while the recording medium is conveyed through the fixing nip portion by rotation of the fixing member and the pressing member, the unfixed toner image is fixed to the recording medium, wherein a plurality of grooves each having a concavely curved section and extending in the circumferential direction or in the rotational axial direction are formed in parallel to each other on the surface of the pressing member so as to create a lenticular lens structure on the pressing member side of a transparent resin layer formed by the resin layer forming portion, and, wherein, pressing the recording medium on one side of which an unfixed toner image is formed at the fixing nip portion between the fixing member and the pressing member, while transferring the transparent resin layer from the pressing member to the other side of the recording medium, the unfixed toner image is fixed on the one side of the recording medium while a lenticular lens is formed on the other side of the recording medium.
