Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a conductive roll that can reduce a stress on toner in a low-temperature and low-humidity environment.SOLUTION: A conductive roll R for an electrophotographic apparatus comprises a surface layer 1. In a surface hardness histogram 10 of the surface layer 1 measured by using an atomic force microscope (AFM), a surface hardness H indicative of a top peak P falls within a range of 10 to 55 MPa, and the area ratio S of a histogram portion with a surface hardness of 45 MPa or less relative to the entirety of the histogram is 65% or more.SELECTED DRAWING: Figure 3 【課題】低温低湿環境下でトナーストレスを抑制することが可能な導電性ロールを提供する。【解決手段】電子写真機器用の導電性ロールＲは、表層１を有している。原子間力顕微鏡（ＡＦＭ）を用いて測定される表層１の表面硬度ヒストグラム１０は、トップピークＰを示すときの表面硬度Ｈが１０〜５５ＭＰａの範囲内にあり、かつ、ヒストグラム全体に対する表面硬度４５ＭＰａ以下であるヒストグラム部分の面積割合Ｓが６５％以上である。【選択図】図３
