CHARGING MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

Provided is a charging member which does not easily oscillate even in cases where a high-frequency alternating current voltage is applied thereto and which is capable of stably charging a photosensitive body. The charging member comprises an electrically conductive base, an electrically conductive elastic layer, and a surface layer. The elastic layer comprises, from the base side, a first rubber layer and a second rubber layer that is arranged on the first rubber layer. When the natural frequency of the first rubber layer is represented by f1 and the natural frequency of the second rubber layer is represented by f2, the natural frequency ratio (f2/f1) is from 2.35 to 10.0 (inclusive).
