Abstract
In one example, a seal for a developer roller in a liquid electrophotographic printer includes an arcuate body curved along a body arc. The body has an inboard face that defines an annular sealing surface along the body arc to contact a face on one end of the developer roller and a guide surface across the body arc at a first end of the annular sealing surface. The guide surface is oriented along a chord of the body arc and intersects the body arc at an obtuse interior angle, to guide any ink encountering the guide surface outward toward the circular outer surface of the developer roller.
