Publication number: 20220342333Abstract: Provided is a toner blend composition comprising a first pigmented toner and a second toner that is devoid of any pigment additive, i.e., a ‘non-pigmented or clear toner’. The non-pigmented or clear toner is about 1% to about 15% by weight of the toner blend composition. The resulting inventive toner blend composition surprisingly exhibits similar print density on a page compared to a fully pigmented toner. Moreover, this toner blend composition exhibits improvement in toner usage per page, thus lowering toner cost compared to a fully pigmented toner. The non-pigmented or clear toner may be used in combination with either a monochrome or conventional toner using a carbon black pigment, or a chemically processed toners (‘CPT”) toners using a black pigment, magenta pigment, yellow pigment or a cyan pigment.Type: ApplicationFiled: April 21, 2021Publication date: October 27, 2022Inventors: KASTURI RANGAN SRINIVASAN, SCOTT DANIEL REEVES

Publication number: 20160363876Abstract: An overcoat layer and method to make an overcoated photoconductor drum of an electrophotographic image forming device using irradiation such as with electron beam (EB) or ultraviolet (UV) light is provided. The photoconductor drum is then cured using EB dose of between 10 and 100 kiloGrays (kGy), preferably between 20 and 40 kGys or UV irradiation with an exposure of between 0.1 and 2 J/cm2. The unique overcoat layer of the present invention is formed having a biphasic morphology comprised of a highly cured crosslinked phase and a second phase enriched in uncured material. The desired amount of uncured uncrosslinked material found in the second phase of the biphasic structure, is between 2-70 wt % range, with particularly good combination of long-life and electrical performance when present at the 5-50 wt % level, and the best performance at the 15-40 wt % level.Type: ApplicationFiled: August 23, 2016Publication date: December 15, 2016Inventors: MARK THOMAS BELLINO, GERALD HUGH CIECIOR, DOUGLAS JEFFREY HARRIS, WEIMEI LUO, BRIAN DAVID MUNSON, DAT QUOC NGUYEN, SCOTT DANIEL REEVES, TANYA YVONNE THAMES

Patent number: 9513591Abstract: An improved overcoat layer for an organic photoconductor drum of an electrophotographic image forming device is provided. The overcoat layer is prepared from a curable composition including a triphenylamine charge transport containing two ethyl acrylate functional groups and a urethane resin containing six radical polymerizable functional groups. The amount of the triphenylamine charge transport containing two ethyl acrylate functional groups in the curable composition is about 20 to about 80 percent by weight. The amount of the urethane resin containing six radical polymerizable functional groups in the curable composition is about 20 to about 80 percent by weight. This overcoat layer improves wear resistance of the organic photoconductor drum without negatively altering the electrophotographic properties, thus protecting the organic photoconductor drum from damage and ultimately providing a photoconductor with a longer useful life when compared to other organic photoconductors commercially available.Type: GrantFiled: December 7, 2015Date of Patent: December 6, 2016Assignee: LEXMARK INTERNATIONAL, INC.Inventors: David Glenn Black, Mark Thomas Bellino, James Alan Hartman, Weimei Luo, Scott Daniel Reeves, Tanya Yvonne Thames
