Abstract
In a thermal fixing system for fixing toner images on the front side of a recording medium in an electrographic printer or copier device, the back side of the recording medium already having a fixed toner image. The thermal fixing means contains a heat transfer fixing station that fixes the toner images on the recording medium, and contains a pre-heating saddle that precedes the heat transfer fixing station in a running direction of the recording medium. A sliding surface that accepts the recording medium over its back side is allocated to the pre-heating saddle. The sliding surface is constructed of a toner-repellant material at least in a contact region with the recording medium. A separating device can separate the recording medium from the saddle.
