Abstract | This electroconductive roll is provided with a core material, a rubber substrate arranged around the core material, and a surface layer arranged around the rubber substrate. The arithmetic mean curvature Spc of the peak on the surface of the surface layer is 1,880 (1/mm) or greater and 14,024 (1/mm) or less, the peak density Spd on the surface of the surface layer is 93,406 (1/mm2) or greater and 151,476 (1/mm2) or less, and the surface area of the surface layer per unit projected area is 1.255 or greater and 5.132 or less.
La présente invention concerne un rouleau électroconducteur qui 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 courbure moyenne arithmétique Spc du pic sur la surface de la couche de surface est supérieure ou égale à 1 880 (1/mm) et inférieure ou égale à 14 024 (1/mm), la densité de pic Spd sur la surface de la couche de surface est supérieure ou égale à 93 406 (1/mm2) et inférieure ou égale à 151 476 (1/mm2), et la superficie de surface de la couche de surface par unité de surface projetée est supérieure ou égale à 1 255 et inférieure ou égale à 5 132.
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。表層の表面の山頂点の算術平均曲Spcが、1,880(1/mm)以上、14,024(1/mm)以下であり、表層の表面の山の頂点密度Spdが、93,406(1/mm2)以上、151,476(1/mm2)以下であり、単位投影面積あたりの前記表層の表面積が、1.255以上、5.132以下である。 |
