ABSTRACT:
An image forming apparatus includes a source of at least one intermediate sheet which is preferably both thermally and electrically conductive. Toner images are transferred from one or more image members to the intermediate sheet under conditions of raised temperature and preferably with the assistance of an electric field. The toner image on the intermediate sheet is then overlaid with a receiving sheet and a combination of heat and pressure transfers and fuses the toner image to the receiving sheet in a single step, preferably while the sheets move at full machine speed. The sheets may then be slowed down or stopped, but are maintained together until cool at which point they are separated and the intermediate sheet fed back to the source of intermediate sheets. The image forming apparatus is particularly useful in creating multicolor toner images with small toners.
