CHARGING MEMBER FOR ELECTROPHOTOGRAPHIC APPARATUS

The purpose of the present invention is to provide a charging member for an electrophotographic apparatus, wherein image defects due to the bleeding of an ion-conductive agent are suppressed, and excellent chargeability can be maintained. Provided is a charging member 10 for an electrophotographic apparatus, the charging member comprising: a base layer 14 composed of a conductive rubber elastomer;and a surface layer 16, wherein the base layer 14 is a crosslinked body of a conductive rubber composition containing a) a crosslinkable rubber, (b) a crosslinking agent, (c) an ion-conductive agentrepresented by general formula (1), and (d) carbon black. R1 and R2 are aryl groups, R3 is a methyl group or an ethyl group, and R4 is C6-8 linear alkyl group. X- is a sulfonate anion having a fluorine atom, or a bis(sulfonyl)imide anion having a fluorine atom. 本发明提供一种能够抑制由离子导电剂的渗出而导致的图像不良并且能够维持优异的带电性的电子照相设备用带电构件。是具有表层16和由导电性橡胶弹性体构成的基层14的电子照相设备用带电构件10，基层14为含有(a)交联性橡胶、(b)交联剂、(c)下述通式(1)所示的离子导电剂以及(d)炭黑的导电性橡胶组合物的交联体。其中，R以及R为烯丙
