Abstract:
1. A device to develop charge images of images to be printed that are generated on a charge image carrier, said development taking place using a developer fluid having at least carrier fluid and toner particles charged to a predetermined charge, in an electrophoretic printing apparatus, comprising: a rotating applicator at a first electrical potential and that accepts developer fluid provided into a developer gap and transports the developer fluid to the charge image carrier; a counter-electrode at a second electrical potential arranged adjacent to the applicator, the developer gap being between the counter-electrode and the applicator, an electrical field that draws the toner particles of the predetermined charge in a direction of the applicator being between the counter-electrode and applicator due to the first electrical potential and the second electrical potential; and a separation electrode protruding into the developer gap at an exit of the developer gap and adjacent to the counter-electrode and the applicator, said separation electrode forming a discharge channel together with the counter-electrode, the separation electrode splitting the developer fluid moving through the developer gap into a first partial flow that remains adjacent to the applicator and a second partial flow that flows away in the discharge channel.
