Abstract

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.
