Abstract
A process and device for fusing toner onto a carrier or a print substrate, in particular a sheet-like print substrate, preferably for a digital printing machine, wherein the toner bearing print substrate is heated by microwaves emanating from at least one microwave emitter in order to melt the toner, and wherein a toner is used that demonstrates a sharp drop-off in the elastic module G' from its solid to its liquid state upon heating. The ratio of the elastic module G' of the toner at the reference temperature, calculated from the initial temperature at the start of the glass transition of the toner plus 50.degree. C., to the value of the elastic module G' at the initial temperature itself is preferably <10.sup.-5.
