    摘要： A contact fuser assembly for use in an electrostatic reproducing apparatus including an internally heated fuser roll structure comprising a rigid or non-deformable, thermally conductive core to which is supplied a low molecular weight polyethylene release material which forms a toner impenetrable layer thereon. Additionally, in order to facilitate stripping of copy sheets from the fuser roll structure, a second release material, for example, talcum powder which is chemically inert and a solid at the operating temperature of the fuser roll structure is applied either to the toner images contained on the copy paper or to the fuser roll structure to thereby provide a layer of the second release material between the fuser roll structure and the toner.

    摘要： An apparatus in which a latent image is developed with marking particles. The marking particles are transported to the latent image. As the marking particles are being moved to the latent image, they are electrically charged. A supply of marking particles is stored and dispensed onto the particle transport. Wrongly charged particles returned to the particle dispenser are electrically discharged.

    摘要： A contact fuser assembly for use in a electrostatic reproducing apparatus including an internally heated fuser roll structure comprising a rigid or non-deformable thermally conductive core capable of interacting with a release material applied thereto in such a manner as to form a thermally-stable interfacial coating intermediate the surface of the core and a release coating comprising portions of the release material. The interfacial coating strongly adheres to the core surface and prevents toner material from contacting the outer surface of the core. The combined coatings have a sub-micron thickness and therefore represent a minimal thermal barrier to the energy being conducted outwardly by the core.
