Abstract
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.
