Abstract
A method of forming a toner image on a receiving sheet includes a step of either transferring or fixing a toner image to the receiving sheet, in which the receiving sheet is heated to a temperature of at least 100.degree. C. To allow steam to escape from the receiving sheet, a gas impermeable layer on the side of the sheet opposite the toner image is made permeable by application of small, closely spaced holes in the layer. The method is particularly usable with a receiving sheet having a heat-softenable layer which is heated beyond its softening point to facilitate transfer of images made up of very small toner particles. The holes are preferably mechanically punched in a curl-preventing layer on the opposite side of the sheet.
