Abstract
Apparatus, methods, and computer-readable mediums are described for adjusting a charge voltage for a photosensitive member to account for accumulated charge quantity. In one example, currents related to charging a charger, which imparts a charge to a photosensitive member, are monitored. Based on the monitored currents, a new charging voltage may be determined and applied that accounts for accumulated charge quantity in the photosensitive member. A transfer current related to a transfer charge may also be monitored or a predetermined value used. The determination of the new charging voltage may be performed at various times.
