Conductive member

Abstract

Provided is such a conductive member that a change in its electrical resistance value caused by its long-term use is reduced to the extent possible. The conductive member has a conductive support and a conductive layer, the conductive layer contains a rubber composition formed of a modified epichlorohydrin rubber, and the modified epichlorohydrin rubber has a unit represented by the following formula (1). In the formula (1), R1, R2, and R3 each independently represent hydrogen or a saturated hydrocarbon group having 1 to 18 carbon atoms.

1 . A conductive member, comprising:
 a conductive support; and   a conductive layer,   wherein the conductive layer contains a modified epichlorohydrin rubber having a unit represented by the following formula (1) and an anion:   
       
         
           
           
               
               
           
         
       
       in the formula (1), R1, R2, and R3 each independently represent hydrogen or a saturated hydrocarbon group having 1 to 18 carbon atoms. 
     
     
         2 . A process cartridge, which is attachably/detachably mounted to a main body of an electrophotographic apparatus, the process cartridge comprising the conductive member according to  claim 1  as at least one member selected from a charging member and a developing member. 
     
     
         3 . An electrophotographic apparatus, comprising the conductive member according to  claim 1  as at least one member selected from a charging member and a developing member.
