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. The apparatus differs from prior practice in that the mix is not removed from the back side of the rolls, but rather is deliberately established in that area, and is caused to sequentially stand in a brush array, turn flat as it moves to an adjacent roller, flip over to an upright position again, and repeat for the number of rolls involved. As such renewal mixing takes place on the back side of the rolls, a renewal supply is caused to cascade over the back to become entrapped with the old mix carried over from the front. |
