Controlling image defects related to transfer or fusing of toner images in an electrostatographic machine, wherein engagement between an operational surface of a toner image bearing member or fusing member and an operational surface of another member forming a nip is adjusted using an engagement adjustment device in order to reduce or eliminate image defects relating to an overdrive or underdrive associated with the nip. The engagement adjustment device provides a preselected amount of overdrive or underdrive between a toner image bearing member or fusing member and a receiver member, which preselected amount includes zero.

A method and apparatus for controlling image defects associated with overdrive or underdrive, and variations thereof, in an electrostatographic machine. A speed modifying force is transmitted to a conformable member that deforms in a nip, thereby inducing strains in the surface of the member at the nip which cancel or controllably reduce the strains caused by engagement in the nip. The speed modifying force may be an externally applied drag force or torque, and may be applied using an open loop or a feedback system including an electromagnetic brake, a motor, etc. The speed modifying force may be applied to a conformable member forming the nip through a redundant linkage of the system that employs gears or other suitable mechanisms.

A process for reducing image defects in an electrostatographic image resulting from particulate contamination. A primary imaging member, including a photoconductive element and an outermost layer of silicon carbide, is uniformly charged in an electrostatographic imaging apparatus subject to particulate contamination. The electrostatographic imaging apparatus includes a charging station, an exposing station, at least one developing station, and a transfer station comprising an electrically biased roller transfer assembly. The primary imaging member is exposed imagewise at the exposing station to form a latent image on the imaging member, which is thereafter developed with toner at the developing station to form a developed image on the imaging member. The primary imaging member bearing the developed image is passed through a charge erasing station to remove residual surface charge, then contacted with a receiver by the electrically biased roller transfer assembly, causing the developed image to transfer to the receiver. The silicon carbide layer protects the photoconductive element against damage by contaminant particles present in the apparatus.

A method for forming a receiver transport member for an electrostatographic reproduction apparatus. The transport member transports receiver members with respect to a fuser assembly and is frictional coupled to a transfer member for driving the transfer member. The method for forming the transport member provides a substrate bearing a high friction layer that includes inorganic particles, with a compound of aluminum selected from the group consisting of aluminum hydroxide, alumina hydrate, aluminum oxide, pseudo-boehmite, boehmite alumina, aluminum salts, and mixtures thereof, dispersed in an organic binder so that the high friction layer is capable of preventing a loss of frictional coupling due to release oil applied to a receiver member bearing a fused toner image.

4301087, 4301371

A method of producing a custom color particulate toner for use in a two-component developer by mixing two or more component color toners. The component color toners are each surface treated with a blend of two or more types of silica particles, which differ in the functional groups appended to them. The silica blend for each component color toner is chosen so that, when the component color toners are mixed together to form the custom color mixture, they will all tribocharge to the same charge-to-mass ratio when mixed with a carrier to form a developer.

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.
