摘要： A charging member is provided which can not easily cause vibration and can stably charge a photosensitive member, even where a high-frequency alternating-current voltage is applied thereto. It is a charging member having an electrically conductive substrate, an electrically conductive elastic layer and a surface layer, and the elastic layer has, in the order from the substrate side, a first rubber layer and a second rubber layer laminated to the first rubber layer, and, where the natural vibration frequency of the first rubber layer is represented by f1 and the natural vibration frequency of the second rubber layer is represented by f2, has a natural vibration frequency ratio, f2/f1, of from 2.35 or more to 10.0 or less.

摘要翻译： 即使在施加高频交流电压的情况下，也能够容易地产生振动并且能够稳定地对感光体进行充电的充电部件。 是具有导电性基板，导电性弹性层和表面层的充电部件，弹性层从基板侧依次层叠有第一橡胶层和层叠到第一橡胶层的第二橡胶层 ，并且其中第一橡胶层的固有振动频率由f1表示，并且第二橡胶层的固有振动频率由f2表示，其固有振动频率比f2 / f1为2.35以上至10.0 或更少。
