摘要： A developer includes black toner particles and carrier particles, the black toner particles including at least one binder, at least one black colorant and one or more external additives, wherein the toner particles comprise from about 7 to about 15 pph of the developer, and wherein the toner particles exhibit a triboelectric charge of from about −25 to about −50 μC/g at toner particle concentrations of about 7 to about 15 pph of the developer. The developer is ideally suited for use in a high speed (greater than 100 prints per minute) semiconductive magnetic brush development apparatus. Preferably, the black toner particles include a styrene acrylate binder, and the external additives include from about 1.3 to about 2.1% by weight of the toner particles of a first silica having an average particle size of from about 35 to about 45 nm, from about 0.5 to about 1.0% by weight of the toner particles of a second silica having an average particle size of from about 135 to about 160 nm, and from about 0.2 to about 0.5% by weight of the toner particles of a titania having an average particle size of from about 35 to about 45 nm, with an external additive toner surface area coverage of from about 25 to about 45%.

摘要： The presently disclosed embodiments relate generally to an image forming apparatus including a delivery member for delivering a functional material in contact with an intermediate transfer belt such that functional material is transferred onto one or more imaging members via the intermediate transfer belt. Embodiments also pertain to an improved electrophotographic imaging member comprising a very thin outer layer on the imaging member surface, where the outer layer comprises functional materials, such as paraffin, that act as a lubricant and or a barrier against moisture and/or surface contaminants. The improved imaging member exhibits improved xerographic performance, such as reduced friction and deletions in high humidity conditions.

摘要： A pair of opposing rollers comprises a first roller and a second roller contacting the first roller to form a nip between the rollers through which print media passes. Because of surface irregularities in the rollers, the nip can have one or more unintended gaps at locations where the surface of the first roller separates from the surface second roller. Further, a frame holds the first roller and the second roller. A manual or automatic axis adjuster is operatively connected to the controller and the first roller. The axis adjuster changes the angle of the axis (a first axis) of the first roller relative to the axis (a second axis) of the second roller based on the gap to position the first axis in a position other than parallel to the second axis. Changing the angle of the first axis relative to the second axis reduces or eliminates the gap.
