Abstract: An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.

Abstract: A nozzle plate for a micro-fluid ejection head, a method of making a hydrophobic nozzle plate, and a method for improving the resiliency of a nozzle plate. The nozzle has a photoimageable hydrophobic polycyclic polyolefin layer derived from an epoxy functionalized polynorbornene.

Abstract: A pigment ink formulation containing a fluorescing material and a method for pigment ink detection are disclosed. Preferably, the fluorescent material is contained in a fluorescent-wax emulsion. The fluorescent-wax emulsion is added into the pigment inks. A detecting unit comprised of an UV LED and a sensor can then be used to detect the fluorescent emission from the pigment inks. The detecting unit can detect all three color inks. The differences in signal detection can be used for ink identification.

Abstract: The present disclosure relates to the use of radiation cured coatings that may be used in a device within an image forming apparatus. The coating composition may include a reactive oligomer capable of radiation curing having a number average molecular weight (Mn) of greater than 1500. A reactive diluent may then be combined with the reactive oligomer, which diluent is also capable of radiation curing and which has a Mn of less than or equal to 1500. The reactive diluent may be present at a level of less than fifty percent by weight of the coating composition. The coating composition may be present at a solids level of 90-100%.

Abstract: Developer roll having a conductive or semi-conductive soft rubber core and a coating deposited in the soft rubber core wherein the coating has a conductive agent. The outer surface of the soft rubber core is modified before the coating is deposited onto the outer surface of the soft rubber core. Methods for making the same.

Abstract: A light-resistant, metal complex dye for inkjet printing comprising a substituted 8-heterocyclic azo-5-aminoquinoline of the following structural formula:

Abstract: Provided is a release agent composition useful in an electrophotographic process. The composition is comprised of certain heat-stable grafted silicone interpolymers. The interpolymers have a melting point such that it is in the form of a liquid on a hot fuser roll, but solidifies to a waxy solid at room temperature. The compositions of the invention were found to reduce transparency streaking in wiper pad systems and when used in felt roll applications, were found to be equal to silicone oil in transmission ratio and transparency streaking. Accordingly, the release agent compositions are especially efficacious in duplex and transparency printing. The release agent compositions of the present invention also exhibit superior release performance and facilitate clean release of toner from fuser rolls in an electrophotographic imaging process.
