1. An electrophotographic member comprising an electro-conductive mandrel and an electro-conductive layer, the electro-conductive layer comprising:
an ion-conductive agent containing at least one anion selected from the group consisting of a fluorinated sulfonylimide anion, a fluorinated sulfonylmethide anion, a fluorinated sulfonate anion, a fluorinated carboxylate anion, a fluorinated borate anion, a fluorinated phosphate anion, a fluorinated arsenate anion, a fluorinated antimonate anion, a dicyanamide anion and a bis(oxalato)borate anion; and
a urethane resin to which a cation of the ion conductive agent is chemically bonded, wherein
the urethane resin has, between two adjacent urethane bonds, (i) a structure represented by structure (1)
—CH2—CH2—CH2—CH2—O—(1)
and (ii) at least one structure of structure (2) or structure (3)
