Patent number: 8688009Abstract: There is described an applicator for use in an image forming apparatus. The applicator includes an applicator comprising an elastomeric matrix and a functional material dispersed therein. The applicator includes an actuator for moving the applicator between a first position having the applicator in contact with a surface, and a second position. The actuator moves the applicator from the first position to the second position at a frequency of from about 10?5 Hz to about 10 kHz wherein the functional material diffuses from the elastomeric matrix to the surface.Type: GrantFiled: June 26, 2012Date of Patent: April 1, 2014Assignee: Xerox CorporationInventors: Yu Liu, Johann Junginger, Gaetano J. Lavigne, Sarah J. Vella, Vladislav Skorokhod, Nan-Xing Hu, Gregory M. McGuire

Patent number: 8404423Abstract: 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.Type: GrantFiled: July 28, 2010Date of Patent: March 26, 2013Assignee: Xerox CorporationInventors: Woo Soo Kim, Gaetano J. Lavigne, Cuong Vong, Johann Junginger, Vladislav Skorokhod, Nan-Xing Hu

Publication number: 20080264796Abstract: 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.Type: ApplicationFiled: April 30, 2007Publication date: October 30, 2008Applicant: XEROX CORPORATIONInventors: Naveen CHOPRA, Jurgen H.
