    摘要: A process for preparing a toner donor roll having an integral electrode pattern involving: (a) providing a cylindrically shaped insulating member; (b) coating the insulating member with a photoresist; (c) patterning the photoresist by exposure to light, resulting in a first photoresist portion corresponding to the electrode pattern and a second photoresist portion corresponding to the remainder of the photoresist; (d) removing the first photoresist portion, thereby exposing the portion of the insulating member to be overlaid with the electrode pattern; and (e) depositing conductive metal on the portion of the insulating member formerly overlaid with the first photoresist portion, resulting in the electrode pattern.

    摘要: This invention is generally directed to toner compositions comprised of a magnetic material and a resin comprising a polymeric esterification product of 1,4-benzenedicarboxylic acid polymerized with 1,2,4-benzenetricarboxylic aicd-cyclic 1,2-anhydride and 2,2-dimethyl-1,3-propane diol. The magnetic material can act as both the colorant and magnetic substance, or an additional colorant such as carbon black can be utilized. The toners of the present invention in one preferred embodiment are useful for developing magnetic images.

    摘要: This invention is generally directed to magnetic toners comprised of a styrene butadiene copolymer resin, and a cubically shaped magnetite material, which toners have a fusing latitude range of at least 30 degrees Fahrenheit up to a maximum temperature of 390 degrees Fahrenheit. Toners having melt fusing temperatures of from about 300 degrees Fahrenheit to about 375 degrees Fahrenheit are desirable. The preferred cubical magnetite used is Mapico Black, which is present in amounts of from about 40 percent to about 70 percent. The toners of the present invention are useful for example in magnetic imaging systems, especially systems employing heat pressure fusing and high speed fusing systems.

    摘要: A method and apparatus for producing a multi-image or multi-color image utilize an intermediate transfer member that is a single layer of fluorocarbon elastomer. The method produces high quality images that do not suffer from image or color shifting or degradation. The single layer intermediate transfer member can contain different zones of electrical properties within the single layer.
