PROBLEM TO BE SOLVED: To provide an electroconductive roll in which the crack of the surface of the electroconductive roll is suppressed more than the case that the aggregation state of particles included in a layer constituting the circumferential surface of the electroconductive roll is not considered.SOLUTION: In the electroconductive roll 10, an elastic layer 14 and a surface layer 16 are stacked on a core body 12. Then, the surface layer 16 contains the particles 16B in a resin material 16A, and contains recesses and projections in a surface thereof. Also, in the surface layer 16, the plurality of particles 16B exist in the projection part Q of the recesses and projections, and a ratio of an area occupied by particles existing in the projection part in a cross-section of the projection part is larger than a ratio of an area occupied by particles existing in a recess part in a cross-section of the recess part. |
