In one embodiment, an image developer includes a developer roller rotatable along a photoconductor for presenting a layer of ink to the photoconductor and a cleaner for cleaning ink from the developer roller. The cleaner includes a first cleaning roller rotatable along the developer roller for removing ink from the developer roller and a second cleaning roller rotatable against the first cleaning roller for mechanically removing ink from the first cleaning roller. In one embodiment, the second cleaning roller deforms against the first cleaning roller such that the cross-sectional length of contact between the first and second cleaning rollers is in the range of 20% to 38% of the circumference of the first cleaning roller. In one embodiment, the second cleaning roller has a density in the range of 90 kg/mto 150 kg/m.

Image developer for presenting ink to a photoconductor

An ink development unit is disclosed for liquid electro photography (LEP) printers or the like. An exemplary squeegee on PIP (photo imaging plate) (or 'SOP') ink development unit for a liquid electro photography (LEP) printer system includes an ink dispenser configured to dispense ink during a printing operation. A developer roller having a compliant surface is positioned in contact with a PIP during a printing operation. The developer roller directly receives the ink dispensed from the ink dispenser. The developer roller squeegees the ink dispensed from the ink dispenser into an ink layer with higher solids concentration for development onto an image area on the PIP.
