Abstract:
1. A charging roller comprising: a conductive shaft; a charge emission member provided to the shaft; and a gap securing member, provided to the shaft, which (i) protrudes toward a photoreceptor drum so as to be closer to the photoreceptor drum than the charge emission member is to the photoreceptor drum and (ii) is in contact with the photoreceptor drum so as to secure a gap between the charge emission member and the photoreceptor drum; a conductive part of the gap securing member and the shaft being boded to each other by electrically releasing adhesive, so that the gap securing member is provided to the shaft; the gap securing member including a ring resin member and a ring conductive member that serves as the conductive part, the conductive member is press fitted in a through-hole on an inner circumferential side of the ring resin member, the shaft is inserted in a through-hole on an inner circumferential side of the conductive member, and the inner circumferential surface of the conductive member and the shaft are bonded to each other by the electrically releasing adhesive.
