An electro-photographic apparatus having a photosensitive body, a plurality of developing units for forming a toner image on a surface of the photosensitive body by attaching toner on a surface of the photosensitive body, a member for receiving a print medium, a first transporting path including a printing portion for transferring one toner image in a substantially vertical direction from the photosensitive body onto one side of the print medium and a fixing portion for fixing the transferred image so as to have a printed print medium and a second transporting path disposed substantially in parallel to and coupled to the first transporting path for returning the printed print medium to the first transporting path for enabling transfer of another toner image on an opposite side on the printed print medium. The printed print medium is transported along the first transporting path for fixing the transferred image on the opposite side of the printed print medium by the fixing portion. The developing units are vertically stacked.
