摘要:
Disclosed is a fluid deposition apparatus comprising (a) a fluid supply, (b) a porous fluid distribution member in operative connection with the fluid supply, enabling wetting of the fluid distribution member with a fluid, and (c) a porous metering membrane situated on the fluid distribution member, whereby the metering membrane enables uniform metering of the fluid from the fluid distribution member onto a substrate.
摘要:
An electrostatographic printing machine and apparatus that utilizes a foam roll aquatron with a hydrophilic web between it and the photoreceptor. The porous web captures and removes toner particles which ordinarily would be trapped in the foam roll nip and cause image quality defects, such as streaking.
摘要:
A power supply for transmitting voltage to a device, comprising: a web including a piezoelectric exterior layer for generating a voltage on the surface thereof in response to being deformed; and means for transferring the voltage on the surface of said piezoelectric exterior layer to the device is disclosed.
摘要:
A colored magnetic toner composition comprised of a polymer resin or resins, an optional waxy, lubricating or low surface energy substance, a colorless or light colored magnetic material, a color pigment, dye or mixture thereof, excluding black, and a whitening agent; and wherein the surface of the toner contains a conductive metal oxide.
摘要:
A toner composition comprised of semicrystalline copolymer resin particles with a melting point of from about 30.degree. C. to about 100.degree. C., and containing functional groups comprising hydroxy, carboxy, amino, amido, ammonium or halo, and pigment particles.
摘要:
In a xerographic printing apparatus, toner material is thermally fused and fixed onto a surface of a copy sheet by condensing water vapor on the surface of the copy sheet. In the preferred embodiment, the toner material substantially comprises docasanoic acid. The water vapor is condensed on the surface of the copy sheet by means of applying the water vapor onto the surface through a narrow slit moving relative to the surface.
