摘要： A method for making a developer roll sleeve in which a core substrate roll is spray coated with a conductive composition including a host resin composition and a wear-resistance imparting additive. Preferably, the host resin composition includes a phenolic thermosetting resin and a conductivity additive such as a carbon black, graphite and the like. Further, the wear resistance imparting additive is preferably selected from the group consisting of a polytetrafluoroethylene resin (e.g., Teflon), graphite, ultra-high molecular weight polyethylene having a molecular weight from about 3,000 to about 4,500 grams, molybedenum disulfide, silicone and mixtures thereof. The wear resistance imparting additive is preferably provided in an amount sufficient to obtain a thickness wear rate of less than about 0.00047 percent per printing cycle.

摘要： A developer roll for use in an electrophotographic printing machine of the type having an electrostatic latent image recorded on a photoconductive member in which a magnetic field attracts magnetic particles to form a magnetic brush on the periphery of a developer roll assembly. The developer roll assembly includes a sleeve and the developer roll. The developer roll is located at least partially within the sleeve. The developer roll includes a core having a core feature and a magnetic member having a member feature. The core feature and the member feature cooperate with each other so that the member and the core are mechanically interlocked with each other.

摘要： An improved document scanning system is realized by using low mass mirrors as optical components. The mirrors consist of a pair of metal structures in honeycomb form sandwiched between a pair of glass skins. The mirrors have a greatly improved stiffness-to-mass ratio compared to conventional mirrors and provide relatively low mass in scan drive components, as well as improved system performance.
