    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: 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.

    摘要: A toner image carrying thermoplastic layer on a receiving sheet is texturized from the back side of the sheet by positioning the sheet between a smooth hard surface and a texturizing surface with the texturizing surface contacting the back side. The thermoplastic layer is softened by heat and becomes texturized without embossing the back side. A curl preventing layer on the back side is not embossed because it has a melting point above the temperature of the process. A glossy-textured print can be produced this way. The process is especially useful in making multicolor prints of photographic quality.

    摘要: A toner image carried on a receiving sheet which receiving sheet includes a heat softenable outer layer is fixed or finished by being fed into a nip between a pair of pressure members. The pressure members either embed the toner in the layer or apply a gloss or texture to the heat softenable layer. To eliminate an image defect at the leading edge of the sheet, the pressure between the pressure members is applied by a means having two conditions, one in which said pressure is applied and a second in which it is relaxed. The sheet is sensed as it approaches the nip and the pressure applied just as or after the nip is reached by the leading edge of the sheet.

    摘要: A toner image carried by a heat softenable layer of a receiving sheet is fixed by feeding it into a pressure nip between a pressure member and a ferrotyping belt. To preheat the heat softenable layer, it is urged against the belt by a pressure or squeegee roller which contacts the back of the receiving sheet and urges it into contact with the belt. The adhesive characteristics of the heat softenable layer when heated by the belt cause the receiving sheet to follow the belt from the squeegee roller into the pressure nip.

    摘要: A toner bearing thermoplastic layer on a receiving sheet is textured or the gloss is improved by heating the thermoplastic layer from the rear to its glass transition temperature and contacting said sheet with a texturizing surface under sufficient pressure to texturize the layer. Offset of the thermoplastitc onto the pressure member contacting it is inhibited by not independently heating that member substantially above the glass transition temperature of the thermoplastic layer.
