Abstract
An apparatus for removing magnetic granules from a moving imaging surface in a region between a developer station and a transfer station is provided. The apparatus includes a removing member located between the developer station and the transfer station. The removing member is rotatable about a longitudinal axis. A groove is located in an exterior surface of the removing member. A portion of the groove extends in a direction skewed to the longitudinal axis of the removing member. The apparatus also includes a a magnetic member which is operatively associated with the removing member. The magnetic member generates a magnetic field to attract the magnetic granules from the imaging surface to the removing member. The removing member and the magnetic member move relatively to one another.
