Abstract
A method and apparatus for charging toner for an imaging device includes an inactivity determining section that determines one or more periods of inactivity of the printing machine, a measuring section that measures a charge of the toner, and a charging section that charges the toner to a predetermined level based on at least one of the determined one or more periods of inactivity and the measured charge of the toner. The toner is charged to a predetermined level after recovery from the inactivity period so that the tribo-electric charge of the toner is enhanced for normal printing without causing unwanted effects when the imagining device recovers from inactivity.
