Abstract: Method and apparatus for printing an image-wise ink pattern on a receiver. A primary imaging member includes a series of substantially equal-sized cells located over the substrate surface thereof. The primary imaging member has an electrically conductive layer. An ink jet printhead selectively ejects drops of ink into the primary imaging member cells in a desired image-wise ink pattern. The image-wise ink on the primary imaging member is fractionated to separate the liquid in the ink. A receiver is transported into operative association with the primary imaging member, and a transfer mechanism applies a pressure between the receiver and the primary imaging member, and establishes an electrostatic field to transfer the image-wise ink pattern to the receiver.

Abstract: A receiver member is provided suitable for having an ultra-gloss, image print formed thereon, the receiver member having at least one planar surface, a plurality of standoffs protruding from the planar surface, the plurality of standoffs providing a coefficient of friction for the planar surface for substantially preventing similar stacked receiver members from sticking together, and without adversely affecting any print image thereon. A member is provided for creating a contour on the receiver member. The member includes a surface contoured to exhibit a plurality of valleys which will not adversely impact print image quality, wherein a reciprocal peaked contour is formed on the receiver member.

Abstract: A monocomponent electrostatographic developer is disclosed. The developer contains a negatively charging toner wherein the toner particle surface contains a positively chargeable inorganic fine powder having a mean volume average diameter of 0.5 to 7.0 &mgr;m, a cleaning ratio of 0.1 to 5.0, and a flowability improving agent having a BET specific surface area of at least 30 m2/g. A method of electrostatic imaging using the developer is also disclosed.
