A charging device includes a charging member and a pulling device. The charging member charges a surface of an image carrier and includes a charging member body and axial-end members. The charging member body is arranged so as to face the image carrier and extends along an axial direction of a rotation shaft of the image carrier. The axial-end members are supported at both ends of the charging member body in the axial direction and do not extend through the inside of the charging member body in the axial direction. The pulling device pulls the charging member in the axial direction.
