Electrophotographic member, method for producing electrophotographic member, and electrophotographic image forming apparatus

An electrophotographic member comprising a base material and an elastic layer on the base material,

• wherein the elastic layer comprises a silicone rubber and an ionic liquid,
• wherein the ionic liquid comprises a cation modified by a dimethylsiloxane chain, and an anion,
• wherein the cation has any of structures represented by structural formulae (1) to (4):
• wherein in the structural formula (1) and the structural formula (2), each of R1 to R3 independently represents an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a hydroxyl group, a benzyl group, a phenyl group or a carboxyl group;
• each of R4 to R6 independently represents an alkyl group having 1 to 10 carbon atoms;
• R7 represents an alkylene group having 1 to 20 carbon atoms and optionally having a substituent, wherein the alkylene group optionally comprises a group selected from the group consisting of phenylene, —O—, —C(═O)—, —C(═O)—O— or C(═O)—NR—, wherein R represents an alkyl group having 1 to 6 carbon atoms;
• and m represents an integer of 1 to 150,
• wherein in the structural formula (3) and the structural formula (4), each R8 independently represents an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a benzyl group or a carboxyl group;
• each of R9 to R11 independently represents an alkyl group having 1 to 10 carbon atoms;
• R12 represents an alkylene group having 1 to 20 carbon atoms and optionally having a substituent, wherein the alkylene group optionally comprises a group selected from the group consisting of phenylene, —O—, —C═O—, —C═O—O— or —C═O—NR—, wherein R represents an alkyl group having 1 to 6 carbon atoms;
• and m represents an integer of 1 to 150, and
• wherein the elastic layer comprises 0.01 to 10 parts by mass of the ionic liquid based on 100 parts by mass of the silicone rubber.
