Abstract: Apparatus for effecting development of an electrostatic latent image comprising a plurality of magnetic developing rollers positioned with intersecting magnetic force fields for effecting a blanket of developing material extending about and between the developing rollers adjacent an electrostatic latent image-bearing surface. A cylindrical roller, which may be electrically biased, is positioned between the magnetic developing rollers adjacent the electrostatic latent image bearing surface to enhance image development.
