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.
Claims20
A charging device, comprising:
- 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.
A charging device, comprising:
- charging means to which a prescribed bias voltage is applied and for coming into contact with an image carrying surface of an image carrier to charge the image carrying surface;
- and
- particle supply means for supplying 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 means.
A charging method, comprising:
- supplying a charging auxiliary particle made of a conductive particle having a diamond particle contained therein in a portion of a charging member coming into contact with an image carrying surface of an image carrier which comes into contact with the image carrying surface to charge the image carrying surface;
- and
- applying a prescribed bias voltage to the charging member in a state that the charging auxiliary particle is mediated between the charging member and the image carrier, thereby charging the surface of the image carrier.
