Abstract
Small particle toner images carried on an image member are transferred to thermally conductive intermediate by heating the intermediate in the presence of an electrical field urging transfer. The intermediate is heated to a temperature sufficient to sinter the toner particles at least when they touch the intermediate and other toner particles, but insufficient to damage the image member or cause the toner to stick to the image member. The toner image is transferred from the intermediate to a receiving sheet, which step can include sufficient heat and pressure to fix the image to the receiving sheet.
