Abstract
A high slope charging device including a DC portion followed by an AC portion. The high slope device includes an insulative shell housing, an electrode and a corona wire. The electrode is coupled to direct current power source which supplies a constant potential to the electrode thereby generating a corona at the electrode. An alternating current power source supplies an alternating voltage to the corona wire. The high slope device beneficially is designed such that both the electrode and the corona wire charge a charge retentive surface to the same potential.
