This charging roller comprises a core material, a rubber material provided on the periphery of the core material, and a surface layer provided on the periphery of the rubber material. The ten-point mean roughness Rz of the surface of the surface layer is 21.0-24.5 μｍ, inclusive. The mean width of the roughness profile elements RSm on the surface of the surface layer is 63.4-87.0 μｍ, inclusive. Ce rouleau de chargement comprend un matériau de noyau, un matériau de caoutchouc disposé sur la périphérie du matériau de noyau, et une couche de surface disposée sur la périphérie du matériau de caoutchouc. La rugosité moyenne en dix points Rz de la surface de la couche de surface est de 21,0-24,5 μｍ, inclus. La largeur moyenne des éléments de profil de rugosité RSm sur la surface de la couche de surface est de 63,4-87,0 µm inclus. 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、２１．０μｍ以上、２４．５μｍ以下である。表層の表面の粗さ曲線要素の平均長さＲＳｍが、６３．４μｍ以上、８７．０μｍ以下である。
