A rotating unit forwards and rewinds a recording medium by rotating in a normal direction and in a reverse direction, respectively. A recording unit records an image on a surface of the recording medium. An erasing unit erases the image recorded on the surface of the recording medium. A shift-amount adjusting unit adjusts a shift amount per unit time of a forwarding portion of the recording medium at a recording position or on an upstream side of the recording position in a forwarding direction. A weight is fixed to the forwarding portion of the recording medium exposed outside from an opening that is provided on a casing.
