Abstract: There is described an a bias charge roller including an electrically conductive core and an outer layer axially supported on the core. The outer layer includes a continuous raised pattern above a non-contact surface wherein the continuous raised pattern includes a contact surface having a height of from about 10 microns to about 40 microns above the non-contact surface. The outer layer transitions from the contact surface to the non-contact surface over a minimum linear distance of 100 microns or greater. The contact surface is configured to contact a charge-retentive surface of an electrophotographic imaging member so as to charge the charge-retentive surface.
