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.
