    • A printer or copier operating according to the transfer printing principle containing an arrangement for printing the front and/or the back of a recording medium. The apparatus contains a photoconductor drum and a thermoadhesive transfer ribbon which is coupled to the photoconductor drum. The transfer ribbon proceeds to a transfer printing and fusing station formed by the transfer ribbon on one side and a heated roller on an opposite side in elastic contact thereto. A first toner image for the back of the recording medium and a second toner image for the front of the recording medium are produced on a photoconductor drum and transferred to the transfer ribbon in this order. The heated roller first receives a toner image for the back of the recording medium. Thereafter, the recording medium is fed to the fusing gap and simultaneous transmission and fusing of the toner image on both sides of the recording medium takes place by the transfer ribbon and the heated roller moving across both sides of the recording medium.

    • A printing or copying machine has a photoconductor (10) with associated recording and developing station (EY, EM, EC, EB) for producing single-color or multi-color toner images on the intermediate image-carrier (10). The toner images are transferred electrostatically, in a transfer zone (T) onto a belt-type transfer element (16) and then, in transfer and fusing zones (U1, U2), printed from the underneath from the transfer element onto the recording carriers (24). In order to facilitate the fusing of the transfer image in the transfer and fusing stations (U1, U2), heating units (23, 31) for heating the toner images on the transfer element (16) and/or for heating the recording carrier (24) are provided. Between the first and the second transfer and fusing station (U1, U2), a turning station (W) is arranged. The printing or copying machine can be operated in the simplex and duplex printing mode of operation to produce single-color or multi-color copies.
