Abstract
An apparatus for removing magnetic carrier beads and similar particles from a photoconductive surface includes a magnetic roller for magnetically attracting and removing the beads from the photoconductive surface. A housing has at least one v-shaped support, and the housing contains the magnetic roller. A back-up shaft is disposed on a side of the photoconductive surface opposite the housing and is supported by the v-shaped support. The shaft and the magnetic roller form a uniform gap having a width of 0.65 +/-0.10 mm.
