Zusammenfassung: | Provided is an electrophotographic electroconductive member, which can be used as a charging member capable of preventing the generation of a ghost image by suppressing discharge omission. As an electrophotographic electroconductive member including an electroconductive support and an electroconductive layer on the support, an electroconductive member is used, in which an electroconductive layer has a matrix comprising a first rubber, and domains dispersed in the matrix, the domains each comprising a second rubber and an electronic electroconductive agent, and for impedance measured by applying an AC voltage with an amplitude of 1 V to the electroconductive layer while varying frequencies between 1.0 × 10-2 Hz to 1.0 × 107 Hz under a specific environment, when a double logarithmic plot with a frequency on an abscissa and an impedance on an ordinate is obtained, a slope on a high frequency side is -0.8 or more and -0.3 or less, and the impedance a low frequency side is from 1.0 × 103 to 1.0 × 107 Ω. |
