A device for driving a charge roller, charge belt, image transfer roller, image transfer belt or similar contact type charging member used to charge an image carrier of an image forming apparatus in contact with the image carrier. The charging member is driven by an exclusive motor independent of a motor for driving the image carrier. A drive gear and a driven gear are formed of metal and resin, respectively. A flywheel is mounted on a drive roller for causing the charging member to rotate. The drive side has greater rotation energy than the driven roller side. A flywheel is also mounted on the drive gear.
