Abstract:
An electro-photographic apparatus, comprising:a photosensitive body in the form of a photosensitive belt disposed for movement along a path in which a major portion of the path extends in a substantially vertical direction; 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, the plurality of developing units being arranged in a vertical stack along one side of the substantially vertical path of the photosensitive body; a transfer unit disposed adjacent to another side of the substantially vertical path of the photosensitive body which is opposite to the one side of the substantially vertical path of the photosensitive body where the vertical stack of the developing units are arranged for transferring the toner image formed on the surface of the photosensitive body onto the transfer unit and thereafter onto a print medium; a fixing unit disposed above the transfer unity for fixing the transferred toner image on the print medium; a paper cassette disposed below the photosensitive body, for accommodating the print medium; a first transporting path along which the print medium is transported in a substantially vertical direction from the paper cassette to the fixing unit via the transfer unit; and a second transporting path disposed substantially in parallel to the first transporting path for returning the print medium with one side thereof printed to the first transportation path so as to enable another toner image to be transferred onto the other side of the print medium.
