SYSTEME ELECTROPHOTOGRAPHIQUE

摘要

An electrophotographic device for a magnetic brush development process in which a conductive material is used for rollers in the conveying mechanism of electrophotosensitive materials which abut on the materials after a charging step by a charging device, but before a developing step by a developing device so as to insulate the rollers from other components. One portion of a shield case of the charging device is insulated from another portion and is electrically connected to the rollers, thereby applying a bias voltage on the rollers using the voltage induced on this portion due to high voltage applied on a corona wire of the charging device.
