Abstract
A roller for improved conditioning of an image formed from a liquid developer comprised of toner particles and liquid carrier. A wire mesh uniformly covering an inner layer of the roller uniformly distributes an electrical bias closer to the surface of the roller and to the adjacent image bearing surface. The electrical bias has the same sign polarity as that of the toner particles of the image, to electrostatically repel and prevent the toner particles from entering the roller, and for compacting the toner particles to the image. The wire mesh reduces the electrical requirements of the materials used for the roller.
