This charging 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 ten-point average roughness Rz of the surface of the surface layer is 12.9-20.3 μm. The average interval Sm between irregularities on the surface of the surface layer is 13.9-28.3 μm. Selon la présente invention, un rouleau de charge 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 de la surface de la couche de surface est de 12,9 à 20,3 µm. L'intervalle moyen Sm entre les irrégularités sur la surface de la couche de surface est de 13,9 à 28,3 µm. 帯電ロールは、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Ｒｚが、１２．９μｍ以上、２０．３μｍ以下である。表層の表面の凹凸平均間隔Ｓｍが、１３．９μｍ以上、２８．３μｍ以下である。
