Summary:PROBLEM TO BE SOLVED: To provide a charging member that can prevent and/or suppress the occurrence of abnormal images and the like, while reducing costs and achieving the long life.SOLUTION: There is used a charging member 201A that is set to have a relationship in which a roughness of a surface of a charging target member 200 facing an image forming area L1 is rougher than a roughness of a surface of the charging target member 200 facing a non-image forming area L2, where the relationship is set by making different the particle diameter and grinding conditions of fine particles PT to be scattered in the image forming area L1.SELECTED DRAWING: Figure 4 【課題】低コスト化とともに長寿命化を得る際に異常画像などの発生を防止および／または抑制できる帯電部材を提供する。【解決手段】被帯電部材２００の画像形成領域Ｌ１に対向する表面粗さが、該被帯電部材２００の非画像形成領域Ｌ２に対向する表面粗さよりも粗くなる関係を設定され、上記関係は、画像形成領域Ｌ１に散在させる微粒子ＰＴの粒径や研削条件を異ならせることにより設定された帯電部材２０１Ａを用いる。【選択図】図４
