  • Publication number: 20130266350
    Abstract: An image forming apparatus includes a fixing unit having a fixing member fixing a toner image onto a recording medium and a fixation pressing member coming into pressure contact with the fixing member to form a fixation pressing area, through which the recording medium passes, between the two members; a transport unit transporting the recording medium output from the fixing unit; and a guide unit disposed between the fixing and transport units and having a substantially arc-shaped transport path along which the output recording medium is guided and transported toward the transport unit. The guide unit has a substantially rib-shaped guide extending along the transport path and coming into contact with the recording medium at a predetermined position of the guide to guide the recording medium, and a recess provided downstream, in a recording-medium transport direction, of the predetermined position and recessed inward from the substantially arc-shaped transport path.

    Abstract: A substrate on which a plurality of thin films having a plurality of cross-sections corresponding to the cross-section of a micro-structure are formed is placed on a substrate holder. The substrate holder is elevated to bond a thin film formed on the substrate to the surface of a stage, and by lowering the substrate holder, the thin film is separated from the substrate and transferred to the stage side. The transfer process is repeated to laminate a plurality of thin films on the stage and to form the micro-structure. Accordingly, there are provided a micro-structure having high dimensional precision, especially high resolution in the lamination direction, which can be manufactured from a metal or an insulator such as ceramics and can be manufactured in the combined form of structural elements together, and a manufacturing method and an apparatus thereof.
