A charging member for an electrophotographic apparatus in which image defects caused by bleeding of an ion-conductive agent are suppressed and excellent chargeability can be maintained. In a charging member for an electrophotographic apparatus including a base layer composed of a conductive rubber elastomer and a surface layer, the base layer is a cross-linked body of a conductive rubber composition containing (a) a cross-linkable rubber, (b) a cross-linking agent, (c) an ion-conductive agent represented by a general formula (1) below, and (d) carbon black. Here, R1 and R2 are allyl groups, R3 is a methyl group or an ethyl group, and R4 is a linear alkyl group having a carbon number of 6-8. X− is a sulfonate anion having a fluorine atom or a bis(sulfonyl) imide anion having a fluorine atom. |
