摘要:
A system and printer are provided for fusing toner on a receiver medium having a toner pile that extends at least about 50 μm above a receiver. In one aspect, a system has a first energy source to apply a first energy to raise a temperature of a first portion of the toner pile to a range of elevated temperature levels below a glass transition temperature of the toner and a second energy source to apply a second energy to raise a temperature of a second portion of the toner pile above the glass transition temperature and to allow the second portion to transfer energy to the first portion. The second energy is provided at a level that allows the transferred energy to raise the temperature of the first portion from the range of elevated levels to a range of temperatures above the glass transition temperature for the toner.

摘要:
Electrophotographic printing of one or more layers of toner to enable the printing of a wide range of toner mass laydown using electrophotography to produce prints with raised letters. This method encompasses the steps of forming multicolor toner images and fusing the print one or more times to create the raised print having the desired height of raised print.

A method of forming a toner image on a receiving sheet includes a step of either transferring or fixing a toner image to the receiving sheet, in which the receiving sheet is heated to a temperature of at least 100.degree. C. To allow steam to escape from the receiving sheet, a gas impermeable layer on the side of the sheet opposite the toner image is made permeable by application of small, closely spaced holes in the layer. The method is particularly usable with a receiving sheet having a heat-softenable layer which is heated beyond its softening point to facilitate transfer of images made up of very small toner particles. The holes are preferably mechanically punched in a curl-preventing layer on the opposite side of the sheet.
摘要:
A method of producing a custom color particulate toner for use in a two-component developer by mixing two or more component color toners. The component color toners are each surface treated with a blend of two or more types of silica particles, which differ in the functional groups appended to them. The silica blend for each component color toner is chosen so that, when the component color toners are mixed together to form the custom color mixture, they will all tribocharge to the same charge-to-mass ratio when mixed with a carrier to form a developer.
摘要:
A method transferring dry toner particles from the surface of an element which has a surface layer comprising polyester or polycarbonate thermoplastic polymeric binder resin matrix to a receiver which comprises a substrate having a polymeric coating on a surface in which the polymeric coating comprises a blend of:(i) from about 40 to about 90 percent by weight based on the total weight of the blend of a thermoplstic addition polymer and(i) from about 10 to about 60 percent by weight based on the total weight of the blend of a thermoplastic addition polymer having a ratio of weight average molecular weight to number average molecular weight in the range of from about 1:1 to 10:1.wherein the Tg of the thermoplastic addition polymers in the blend is less than approximately 10.degree. C. above the Tg of the toner binder and the surface energy of the thermoplastic polymer coating is approximately 38 to 43 dynes/cm by contacting the toner particles with the receiver which is heated to a temperature such that the temperature of the thermoplastic polymer coating on the receiver substrate during transfer is at least approximately 5.degree. C. above the Tg of the thermoplastic addition polymers in the blend. After transfer, the receiver is separated from the element while the temperature of the thermoplastic polymer coating is maintained above the Tg of the thermoplastic addition polymers.
