摘要： A method and an apparatus of fixing a heat curable toner to a carrier substrate are shown. In the method, a toner applied to a first surface of the carrier substrate is heated above the glass transition temperature of the toner by microwave radiation, using at least one microwave applicator as a first heat source, to thereby initiate thermal cross-linking of polymer chains of said toner. The temperature is kept above the glass transition temperature of the toner for a predetermined time of at least one second, by applying heat to the toner by means of at least one non-contact second heat source, to thereby allow the thermal cross-linking to proceed further and to thereby raise the glass transition temperature of the toner. The apparatus has at least one microwave applicator forming a first heat source, at least one second heat source for heating the toner and/or the carrier substrate, at least one transport mechanism for contacting the carrier substrate on a second side thereof and for transporting the carrier substrate in sequence along the first and second heat sources and at least one controller for controlling the first heat source, the second heat source and/or the transport mechanism such that toner on a first side of the carrier substrate is heated above its glass transition temperature and kept at a temperature above the glass transition temperature for at least one second.
