Abstract
The electrophotographic member includes an electroconductive substrate and an electroconductive surface layer. The surface layer contains an electroconductivity imparting agent and a polyrotaxane including a first and a second polyrotaxane molecule. The first polyrotaxane molecule includes a first cyclic molecule, and the second polyrotaxane molecule includes a second cyclic molecule. The cyclic molecules of the first and the second polyrotaxane molecules are bound in such a manner that the oxygen atom of a hydroxy group of the first cyclic molecule and the oxygen atom of a hydroxy group of the second cyclic molecule are bound with a structure represented by the following formula (1):*—R—Z—R—** In this formula, z represents a linking group, and '*' and '**' represent binding sites to be bound to either of the oxygen atoms derived from the hydroxy groups of the first and the second cyclic molecule. Rand Reach represent a specific structure.
