摘要： A receiver having an image side and a non-image side bent in a bend area including a bend axis. Toner is deposited on the image side of the receiver in the bend area using an electrophotographic print engine. The deposited toner is fused to the receiver. During or after fusing, the fused toner is heated to a selected fusing temperature greater than or equal to the Tg of the toner. A heat-shrinkable film is affixed to the heated toner after heating the toner, wherein the Tg of the film is greater than the Tg of the toner. The toner is cooled below its Tg after affixing the film. The bend area of the receiver is reheated after cooling the toner, so that the temperature of the heat-shrinkable film rises above its Tg, the heat-shrinkable film contracts, and the receiver bends at the bend axis.

摘要： A method and apparatus for fusing a heat curable toner to a carrier sheet having said toner thereon. In the method, the toner is sandwiched between said carrier sheet and a movable fuser belt and heated to a first temperature by a first means, which first temperature is above a first glass transformation temperature of the toner. The toner is kept at an elevated temperature for a predetermined time by a second means, which elevated temperature is above the first glass transformation temperature, thereby raising the glass transformation temperature of the toner to a second glass transformation temperature. The apparatus has at least a first endless fuser belt, first heating means for heating the toner to a first temperature, second heating means located downstream of said first heating means for keeping the toner at an elevated temperature for a predetermined time and control means for controlling the first and second heating means.

摘要： The present invention is a method for the preparation of electrostatographic toner including the following steps. A first dispersion is prepared with a solvent, a silicone wax, and a hyperdispersant. The first dispersion is added to an organic solvent containing a polymer material to form an organic phase. The organic phase is dispersed in an aqueous phase containing a particulate stabilizer to form a second dispersion. The second dispersion is homogenized. The organic solvent is evaporated from the second dispersion and the resultant product is recovered, washed and dried. In an alternate method the hyperdispersant is added directly to the organic phase before mixing with the aqueous phase.
