Abstract:
1. Method for fixing toner images applied to a substrate on a first-side and a second-side of a substrate comprising the steps of: the toner images applied on the first-side and second-side are fixed together by microwaves, being heated to a final fixation temperature, and the toner image applied on the first-side is prefixed by microwaves before a toner image is applied on the second-side, with the toner image of the first-side being heated to a prefixing temperature that is lower than the final fixing temperature, wherein the ratio of the modulus of elasticity G′ at a reference temperature, calculated from the initial temperature at the beginning of the glass transition point of the toner plus 50° C. to the value of the modulus of elasticity at the initial temperature is <10
