Abstract
A electrophotographic image fixing device fixes a toner image on a substrate. The substrate is passed between two pressing rollers disposed in opposition to each other to fix toner images on the substrate. The pressing rollers includes a surface constructed from an elastic material layer such that the elastic material layer can be deformed approximately 0.5-1.5% in terms of thickness. The pressing force against the toner applied side of the substrate is adjusted to 0.3-1 kg/cm.sup.2. As a result, an image with excellent toner fixing strength can be formed on a substrate such as an envelope without wrinkling the substrate during the fixing operation.
