Abstract
A process and apparatus for heat-fixing a heat-fixable material to a carrier in which process the heat is generated by contact between the side of the carrier face from the material and a friction element during relative motion of the carrier and the element. The apparatus includes a friction roller or belt around which the carrier is partly wrapped and which can be rotated relative to the carrier by a driving motor. The roller may comprise a material or low heat conductivity having a thin wall with the interior being filled with insulating material. The apparatus also may include a probe for measuring the temperature of the carrier material in or immediately after contact with the friction element.
