  • Publication number: 20130029818
    Abstract: The present invention is a sleeved roller for use in an electrostatographic machine. The roller includes a cylindrical rigid core member having an outer ceramer surface. A removable sleeve member includes a substrate comprising a polymeric material support layer, wherein the sleeve member surrounds and intimately contacts the outer ceramer surface. The invention provides a low cost sleeved roller, while providing a high friction interference fit to reduce slipping of the sleeve member during operation and thereby providing improved registration performance.

  • Patent number: 8170441
    Abstract: A cleaning blade member including a polymer substrate and a fluorinated polyurethane ceramer coating surface layer. The polymer substrate may comprise polyurethane. The fluorinated polyurethane ceramer coating may comprise a fluorinated polyurethane silicate hybrid organic-inorganic network formed as a reaction product of a fluorinated polyurethane having terminal reactive alkoxysilane groups with a tetraalkoxysilane compound. The fluorinated polyurethane ceramer coating may be coated on the polymer substrate of the cleaning blade without any primer layer therebetween. Also described is an electrostatographic apparatus comprising a toner-contacting member and such a fluorinated ceramer coated cleaning blade for the toner-contacting member. The toner-contacting member may comprise an endless transport web. The fluorinated ceramer enhances the ability of particles to be released from the surface therefore reducing contamination generated due to particles attached to the surface.

  • Patent number: 7976658
    Abstract: The present invention is a process for making an intermediate transfer member. The process includes forming an endless belt by seaming two ends of a substrate material to form a seam. A smoothing layer is applied on top of the endless belt using a rotary cast process wherein said intermediate transfer member has a continuous seamless top surface. In a preferred embodiment the endless belt is formed by adhering at least two layers of a substrate to form a belt having an inner and outer seam.

  • Patent number: 7955527
    Abstract: The invention provides a conductivity control agent comprised of a polymeric material containing diphosphonium bis(sulfoarylcarbonyloxy) glycol salts as conductivity control agent. The conductivity control agents can be used with semi-conductive rolls, belts and other biasable members. The inclusion of the conductivity control agent in the polymeric or polyurethane elastomers extends the electrical life of the polymeric biasable member in low humidity environments. Additionally, the resistivity of the elastomeric polymer on the biasable member is controlled to a desirable value by adjusting the conductivity control agent level in the elastomers.

  • Publication number: 20090116882
    Abstract: The present invention is a method of forming a toner image on a receiving sheet. The method includes forming an electrostatic image on a primary image member and toning the image with a dry toner to form a toner image. The toner includes toner particles having a diameter of between 4 and 10 microns and transfer assisting particles appended to the toner particles surface. The transfer assisting particles have a diameter of between 20 and 100 nm. The toner image is transferred from the primary image member to an intermediate image member having an overcoat layer, the overcoat layer having a Young's modulus of from 250 to 500 MPa. The toner image is transferred from the intermediate image member to a receiving sheet wherein the intermediate image member drives the primary image member or the receiving sheet.
