Title (EN) ELECTROCONDUCTIVE ROLL
(FR) ROULEAU ÉLECTROCONDUCTEUR
(JA) 導電性ロール
Abstract:
(EN) An electroconductive roll provided with a core material, a rubber substrate arranged around the core material, and a surface layer arranged around the rubber substrate. The ten-point average roughness Rz on the surface of the surface layer is 3.9 to 11.7 μm inclusive. The average convex-concave interval Sm on the surface of the surface layer is 9.9 to 20.8 μm inclusive.
(FR) Selon la présente invention, un rouleau électroconducteur est pourvu d'un matériau de noyau, d'un substrat de caoutchouc disposé autour du matériau de noyau, et d'une couche de surface disposée autour du substrat de caoutchouc. La rugosité moyenne en dix points Rz sur la surface de la couche de surface varie de 3,9 à 11,7 μm inclus. L'intervalle convexe-concave moyen Sm sur la surface de la couche de surface varie de 9,9 à 20,8 µm compris.
(JA) 導電性ロールは、芯材と、芯材の周囲に配置されたゴム基材と、ゴム基材の周囲に配置された表層とを備える。表層の表面の十点平均粗さRは、3.9μm以上、11.7μm以下である。表層の表面の凹凸平均間隔Sは、9.9μm以上、20,8μm以下である。
