Abstract

Undesirable foreign particles can become attached to the electrophoretic imaging roll surface in an electrophoretic imaging system, and these particles disturb the uniform geometry of the blocking-web-inkconductive web sandwich and cause image defects. This sandwich is held away from the image roll by these particles, which thereby results in a lower field producing low density spots in the image. To avoid this, there is used a biased roller to pick off these particles and deposit them on the portion of the blocking web downstream of the image roll.
