  In order to maintain the image quality of a recent high-speed electrophotographic apparatus, a charging member is provided which hardly causes charging unevenness of a photosensitive member even when vibration of the photosensitive member occurs. The charging member includes an electro-conductive support, an electro-conductive elastic layer, and a surface layer. The elastic layer contains a resin having an epichlorohydrin chain in the molecular structure and a specific flavonoid compound having two or more hydroxyl groups in the molecular structure.

  为了保持最新高速电子照相设备的图像质量，提供了一种充电构件，即使感光构件发生振动，也几乎不会造成感光构件充电不均匀。充电部件包括导电支架、导电弹性层和表面层。弹性层包含分子结构中具有环氧氯丙烷链的树脂和分子结构中具有两个或两个以上羟基的特定黄酮类化合物。
