Abstract
An electroconductive roll includes a core member, a rubber base material disposed around the core member, and a surface layer disposed around the rubber base material. The arithmetic mean peak curvature Sof a surface of the surface layer is equal to or greater than 1,880 (1/mm), and is equal to or less than 14,024 (1/mm) The density of peaks Sof the surface of the surface layer is equal to or greater than 93,406 (1/mm), and is equal to or less than 151,476 (1/mm). The surface area of the surface layer per unit projected area is equal to or greater than 1.255, and is equal to or less than 5.132.
