Patent ID: 11619890

Abstract:
The electro-conductive member has an electro-conductive support, and an electro-conductive layer, in which the electro-conductive layer has a matrix including a first rubber cross-linked product and domains dispersed in the matrix, each of the domains includes a second rubber cross-linked product and electro-conductive particles, an outer surface of the electro-conductive member has concave portions, a surface of at least a part of the domains is exposed to the outer surface of the electro-conductive member at bottom portions of the concave portions, a volume resistivity of the matrix is greater than 1×1012 Ωcm, a volume resistivity of the electro-conductive layer is 1×105 Ωcm to 1×108 Ωcm, and A2 is 20 times or more of A1.
