Abstract
A printing apparatus having an imaging member having an external surface and a series of substantially equal sized cells located over such surface. The printing apparatus includes an ink jet device for selectively ejecting droplets of ink, having marking particles and liquid, into the cells of said imaging member in a desired image-wise ink pattern, a mechanism for filling the cells of said imaging member with a dielectric fluid after said ink jet device ejects droplets of ink into said cells, and transfer mechanism including a device for fractionating the marking particles in the ink from the liquid and transferring the image-wise marking particle pattern to a receiver member.
