Abstract
An electrophotographic member, comprising: a support member having a conductive outer surface; and a conductive layer disposed on an outer surface of the support member, wherein the conductive layer comprises a matrix comprising a first rubber, and a plurality of domains dispersed in the matrix, volume resistivity of the matrix is 1.00×10Ω·cm or less, the plurality of domains comprise at least one domain A, and the domain A satisfies specific conditions, in a case where impedance of the electrophotographic member is measured by applying specific AC voltage while changing frequency in a range of 1.0×10to 1.0×10Hz and the specific plotting is done, a slope at a specific frequency is −0.80 to −0.30, and the impedance in a specific frequency is 1.00×10to 1.00×10Ω.
