Abstract

A method for fixation of toner on a carrier or printing stock wherein the printing stock with toner is exposed to at least one radiation pulse or radiation flash of electromagnetic radiation and heated for melting of the toner, and a toner having a sharp transition from its solid to liquid state when heated is used. The toner is preferably characterized by the ratio of the value of the elastic modulus G', at 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 itself, is less than 10−5.
