Abstract
Aspects of the invention relate to hard imaging device charging systems, liquid electrophotography charging systems, hard imaging apparatuses, and hard imaging device electrophotography charging methods. In one embodiment, a hard imaging device charging system is described. The charging system may include a first charging device configured to charge a respective first region of a cylindrical image bearing member used to form latent images during hard imaging operations of the hard imaging device. The charging system may also include a second charging device configured to charge a respective second region of the cylindrical image bearing member used to form latent images during hard imaging operations of the hard imaging device. The first and second regions may have different radii from a central axis of the cylindrical image bearing member.
