Abstract
A bias charge roller includes an electrically conductive core. An outer layer is axially supported on the core. The outer layer is either conductive or semi-conductive. The bias charge roller further includes a continuous raised pattern on the outer surface of the outer layer. The continuous raised pattern is configured to contact a charge-retentive surface of an electrophotographic imaging member so as to charge the charge-retentive surface. The bias charge roller can be employed in an image forming apparatus.
