Charging roll whose resistance adjusting layer contains insulating particles dispersed therein |
摘要 |
<p>A charging roll comprising: a center shaft(10); an electrically conductive rubber layer (12) formed on an outer circumferential surface of the center shaft and having a relatively low hardness; a resistance adjusting layer (16) formed radially outwardly of the conductive rubber layer; and a protective layer (18) formed radially outwardly of the resistance adjusting layer. The resistance adjusting layer is formed of a rubber composition prepared by mixing a rubber material with particles of an electron-conductive material and particles of an electrically insulating material. The rubber composition comprises 10-50 parts by weight of the electrically insulating material per 100 parts by weight of the electron-conductive material. <IMAGE></p> |
