Abstract

Cleaning apparatus for removing residual single component magnetic toner from a charge retentive surface. The cleaning apparatus comprises a magnetic cleaning roller and a magnetic image disturber, the latter of which includes a pair of blade members which are spacially oriented so that two adjacent ends thereof form a gap therebetween which is disposed adjacent the charge retentive surface. The opposite ends of the blade members are disposed adjacent the magnetic roller such that upon rotation of the roller a pulsating magnetic field is created across the gap.
