Abstract
An electrophotographic member including 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 includes a matrix including a first rubber, and at least one domain dispersed in the matrix, volume resistivity of the matrix is 1.00×10to 1.00×10Ω·cm, the at least one domain includes a domain A including a second rubber and an electronic conductive agent; the conductive layer further includes an insulating region including a third rubber; in a case where impedance of the electrophotographic member is measured under specific conditions, impedance X at a specific frequency is 1.00×10to 1.00×10Ω; and a relationship between impedance Y under specific frequency and the impedance X satisfies X/Y≥7.5.
