摘要： A charging device and method in which a charging member, for example, of a brush, plate, film or roller type, for charging a charge-receiving member is disposed at a predetermined distance from the charge-receiving member. The distance is adjusted at not greater than a discharge start distance when the discharge is started and is adjusted at greater than the discharge start distance and less than a discharge stop distance after the discharge is started. The discharge start distance is the distance at the start of discharge when two electrodes are in close proximity as a voltage is applied, and the discharge stop distance is the distance directly before a stable discharge stops when two electrodes are separated while in state of discharge.
