(ii) reacting an amine compound with the unmodified epichlorohydrin rubber to obtain a modified epichlorohydrin rubber having units represented by said formulae (3) and (4), and formula (1);

OG Complex Work Unit Drawing
in which R1, R2, and R3 each independently represent hydrogen or a saturated hydrocarbon group having 1 to 18 carbon atoms; and
(iii) heating the modified epichlorohydrin rubber on the periphery of a mandrel to at least 160° C. to remove unreacted amine compound, and vulcanizing the modified epichlorohydrin rubber to obtain the conductive layer, wherein
the step (iii) is performed after the step (ii), and
the amine compound has a boiling point of 160° C. or less.
