A charging member is provided, in which the electrical resistance is controlled with ease, the electrical resistances are uniform, and the electrical resistance, chemical properties, mechanical properties, etc., are suppressed to change with time so as to exhibit superior durability. The charging member primarily contains 100 parts by weight of at least one kind of polar rubber including at least a nitrile rubber, and further contains at least 0.01 parts by weight or more and 5 parts by weight or less of diazabicycloamine compound and 0.01 parts by weight or more and 10 parts by weight or less of weakly acidic compound.
