Abstract
A process or device for fusing toner on a carrier or a printing material, particularly a sheet-type printing material, preferably for a digital printer, wherein the printing material with the toner is irradiated with microwaves from at least one microwave conductor, which is heated to melt the toner and a toner is used which shows a sharp drop of the elastic modulus G′ from its hard state to its liquid state when heated. The ratio of the value of the elastic modulus G′ of the toner is the reference temperature value calculated from the initial temperature at the beginning of the glass transition of the toner plus 50° C. to the value of the elastic modulus G′ at the initial temperature is <10 .
