  • Patent number: 8404423
    Abstract: The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrophotographic, including digital apparatuses. Embodiments pertain to an improved electrophotographic imaging member used in customer replaceable units (CRU) comprising a very thin outer layer on the imaging member surface, where the outer layer comprises healing materials that act as a barrier against moisture and/or surface contaminants. The improved imaging member exhibits improved xerographic performance, such as reduced wear and deletions in high humidity conditions.

  • Patent number: 7645560
    Abstract: An image forming medium includes a substrate, and an imaging layer coated on or impregnated into the substrate, wherein the imaging layer includes an imaging composition including a photochromic or photochromic-thermochromic material and an infrared absorbent dissolved or dispersed in a solvent or polymeric binder; wherein the infrared absorber absorbs infrared light of a wavelength in a range from about 730 nm to about 1500 nm; and wherein the imaging composition is imageable by light of a first wavelength and erasable in a short time period by a combination of infrared radiation and light of a second wavelength and exhibits a reversible transition between a colorless and a colored state.

  • Publication number: 20080264796
    Abstract: A lateral wire apparatus allows direct lateral viewing of particles of electrophoretic ink (e.g., liquid emulsion aggregation particle (LEAP) ink) that are undergoing electrophoretic migration. Electrophoretic ink movement is commonly monitored by placing the ink through the top electrode, but as the toner particles migrate back and forth between the two electrodes, the viewer can not see what lies beneath the top electrode. This may hide commonly known failure modes, such as particle agglomeration, swishing of particles due to hydrodynamic effects. The lateral wire apparatus includes two narrow gauge wires glued to a glass substrate and held apart at a fixed distance to help maintain a uniform electric field across the gap. A plastic block with pegs that situated at a fixed distance and threaded screws is used to make the lateral wire apparatus with precise wire spacing that may be reproducibly made in less than five minutes using inexpensive and readily available materials.
