Disclosed is a porous, partially evacuated drive roll to improve belt drive performance in liquid ink development (LID) marking systems. Surfaces within LID marking modules are usually wet with dispersant liquid, so dispersant films often form on the backs of photoreceptor and other process belts. Occasionally, this occurs despite the design intent, and occasionally such films are advantageous as boundary layer lubricants to aid belt motion. However, such films can interfere with the operation of drive rolls which may slip against them.
