Abstract
A toner image carried by a heat softenable layer of a receiving sheet is fixed by feeding it into a pressure nip between a pressure member and a ferrotyping belt. To preheat the heat softenable layer, it is urged against the belt by a pressure or squeegee roller which contacts the back of the receiving sheet and urges it into contact with the belt. The adhesive characteristics of the heat softenable layer when heated by the belt cause the receiving sheet to follow the belt from the squeegee roller into the pressure nip.
