ABSTRACT:
A technology capable of realizing a stable charging performance in an image forming apparatus employing a contact charging system is provided. A charging device is configured to have a charging member to which a prescribed bias voltage is applied and which comes into contact with an image carrying surface of an image carrier to charge the image carrying surface; and a particle supply section configured to supply a charging auxiliary particle made of a conductive particle having a diamond particle contained therein in a portion coming into contact with the image carrying surface in the charging member.
