Electrophotographic member and electrophotographic image forming apparatus

An electrophotographic image forming apparatus comprising an intermediate transfer member, wherein

• the intermediate transfer member is an electrophotographic member, wherein
• the electrophotographic member comprises a base layer and an elastic layer on the base layer, wherein
• the elastic layer comprises a rubber mixture comprising rubber as a matrix, an anion, a cation, and an inorganic layered double hydroxide compound, wherein
• the anion is at least one selected from the group consisting of structural formulae (1) to (3),
• the cation is at least one selected from the group consisting of structural formulae (4) to (7), and
• the inorganic layered double hydroxide compound has an average value of interlayer distances of 4 Å or larger and 8 Å or smaller, which are measured by XRD:
• (wherein in structural formula (3), X represents a halogen element;)
• (wherein in structural formulae (4) and (5), R1 to R4 each independently represent an alkyl group having 6 to 16 carbon atoms, an alkoxy group having 6 to 16 carbon atoms, a hydroxyl group, a phenyl group, a benzyl group or a carboxyl group;)
• (wherein in structural formulae (6) and (7), R5 to R7 each independently represent an alkyl group having 4 to 16 carbon atoms, an alkoxy group having 4 to 16 carbon atoms, a hydroxyl group, a phenyl group, a benzyl group, or a carboxyl group;
• R8 to R10 each independently represent an alkyl group having 1 to 16 carbon atoms;
• R11 represents an alkylene group having 1 to 16 carbon atoms, which optionally has a substituent;
• the alkylene group optionally has a structure through a group selected from the group consisting of -Ph-, —O—, —C(═O)—, —C(═O)—O—, and —C(═O)—NR— (where R represents an alkyl group having 1 to 6 carbon atoms);
• and
• m represents an integer of 1 or more and 16 or less.).
