摘要： A charger is provided. The charger includes a discharge electrode, a cleaner, and a holder. The discharge electrode is composed of a wire, and the wire has a surface plated with palladium. The cleaner removes foreign substances adhered to the discharge electrode. The cleaner includes a first cleaner composed of a glass-containing resin and a second cleaner. The first cleaner scrapes off the foreign substances by press-contacting the wire while moving, and the second cleaner wipes off the foreign substances by press-contacting the wire while moving. The holder movably holds the cleaner in a direction parallel to the discharge electrode.
