Electroconductive roll

To provide an electroconductive roll (R) with which it is possible to suppress toner stress in a low-temperature, low-humidity environment. An electroconductive roll (R) for an electrophotographic device, the electroconductive roll (R) having a surface layer (1). In a surface hardness histogram (10) of the surface layer (1) measured using an atomic force microscope (AFM), the surface hardness (H)at the top peak (P) is in the range of 10-55 MPa, and the area ratio (S) of the histogram portion corresponding to a surface hardness of 45 MPa or below in relation to the entire histogram is 65% or above. 本发明提供种在低温低湿环境下能够抑制调色剂压力的导电性辊(R)。电子照相设备用的导电性辊(R)具有表层(1)。使用原子力显微镜(AFM)测定的表层(1)的表面硬度直方图(10)中，表示最大峰值(P)时的表面硬度(H)处于10～55MPa的范围内，并且，表面硬度为45MPa以下的直方图部分相对于直方图整体的面积比例(S)为65％以上。
