Publication number: 20150185641Abstract: 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: December 31, 2013Publication date: July 2, 2015Applicant: Lexmark International, Inc.Inventors: Mark Thomas Bellino, Gerald Hugh Ciecior, Douglas Jeffrey Harris, Weimei Luo, Brian David Munson, Dat Quoc Nguyen, Scott Daniel Reeves, Tanya Yvonne Thames

Publication number: 20150185631Abstract: An 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 hexyl-based urethane resin having six radical polymerizable functional groups and a charge transport molecule having at least one radical polymerizable functional group. The amount of the hexyl-based urethane resin having six radical polymerizable functional groups in the curable composition is about 20 percent to about 80 percent by weight. The amount of the charge transport molecules having at least one radical polymerizable functional group in the curable composition is about 20 percent 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 extending its service life.Type: ApplicationFiled: December 27, 2013Publication date: July 2, 2015Applicant: LEXMARK INTERNATIONAL, INC.Inventors: David Glenn Black, James Alan Hartman, Weimei Luo, Scott Daniel Reeves

Each occlusion member is mounted on an axle, with one end of the axle mounted on the first gear and an opposite end of each axle engaged by a support member. Two support ribs are mounted between the gear and the support element. The pair of occlusion members includes a first pair of rollers mounted on the gear 180° apart from each other. The two support ribs are mounted on the gear 180° apart from each other and offset 90° from the pair of rollers. The DC motor drives a worm gear in meshed engagement with the gear of the pump mechanism.Type: GrantFiled: May 1, 2009Date of Patent: October 23, 2012Assignee: Xerox CorporationInventors: Joseph Benjamin Gault, Michael Cameron Gordon, Barry Daniel Reeves
