摘要： To create an overcoat on a toner image, a clear heat softenable particulate material is applied to a fusing surface before the fusing surface contacts the toner image in a fusing nip. The particulate material softens in the fusing process and ends up as a clear overcoat for the toner image, protecting it from scratches, fingerprints, deglossing and/or softening from heat.

摘要： 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.

摘要： A method is provided for transferring electrostatically charged thermoplastic toner particles having a particle size less than about 8 micrometers from an element to a receiver within a transfer zone. The receiver is heated and contacted with the electrostatically charged toner particles on the element at a temperature sufficient to adhere the particles to one another at their points of contact, but insufficient to cause the toner particles to flow into a single mass. An electric field tending to force the charged toner particles toward the receiver is simultaneously applied to the transfer zone. The receiver is subsequently separated from the element.

摘要： 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.
