Abstract
A device for the pressure fixing of a toner on a record carrier under ambient temperatures has a stand; a first pressure roll of relatively large diameter rotatably and stationarily supported in the stand; and a second pressure roll of relatively small diameter rotatably supported in the stand and cooperating with the first pressure roll to define therewith a roll gap. The second pressure roll is displaceably supported to be shiftable towards and away from the roll gap. The device further has a plurality of pressure rollers arranged in a series along the length dimension of the second pressure roll in an axially parallel orientation therewith and a support for individually displaceably supporting each pressure roller for movement towards and away from the roll gap. A separate spring urges each pressure roller into contact with the second pressure roll for exerting thereon a pressing force with which the first and second rolls compress a record carrier passing through the roll gap. With each pressure roller there is associated a setting mechanism for individually adjusting the pressing force exerted by each pressure roller.
