Abstract
A magnetic roll having longitudinal grooves machined in its rotating sleeve enables a pair of rolls to be rotated in a direction opposite to the direction of a photoreceptor moving through a development zone and a trim blade to be mounted proximate one of the rolls at a trim gap of approximately 0.5 to 0.7 mm. The magnetic roll includes a stationary core with at least one magnet, and a sleeve having longitudinal grooves that is mounted about the stationary core so that the sleeve rotates about the stationary core. The sleeve has a relatively smooth surface area between the grooves.
