    Abstract: Provided is an electro-conductive member for electrophotography that stably shows high electroconductivity even under a low-temperature, low-humidity environment. The electro-conductive member for electrophotography has an electro-conductive mandrel and an electro-conductive layer. The electro-conductive layer contains an ionic electro-conductive resin and an ion carrier. The ionic electro-conductive resin has at least one structure selected from the group consisting of structures represented by the following formulae (1), (2), (3), and (4), and a structure represented by the following formula (5) (in the formula (1) to the formula (5), R 1 , R 2 , R 3 , and R 4 each represent a divalent organic group, X 1 , X 2 , X 3 , and X 4 each independently represent a sulfonic group or a quaternary ammonium base, and 1 represents an integer of 1 or more and 23 or less).
