A fixing device is provided with a fixing device body, a fixing member, and a first attachment section. The fixing device body is adapted to attach to and detach from an apparatus body of a double-sided image forming apparatus, which has a return passage through which a recording medium is returned to an image forming position, and an apparatus body of a single-sided image forming apparatus, which does not have the return passage. The first attachment section is provided at a return passage side in the fixing device body, and is adapted to have a passage surface member, which has a passage surface of an introduction passage through which a fixed recording medium is introduced into the return passage, attached thereto.

A printer apparatus including a printing-medium conveying unit conveying a printing medium, a sheet conveying unit conveying a thermal transfer sheet having an image protecting layer to be thermally transferred onto an image formed on the printing medium, a thermal head with heating elements linearly arranged in a direction orthogonal to a conveyance direction of the printing medium, and a control unit driving and controlling the thermal head. For selectively applying different amounts of thermal energy to the heating elements to form an uneven pattern on the image protecting layer thermally transferred onto the image on the printing medium, the control unit randomly divides a row of the heating elements into heating element groups each including at least two adjacent heating elements, applies the same amount of thermal energy to heating elements in the same heating element group, and applies different amounts of thermal energy to adjacent heating element groups.
