Abstract:
1. An electrophotographic member comprising a surface layer, wherein the surface layer comprises a modified polysiloxane having a structure represented by the following formula (1): wherein, in the formula (1), G represents a bivalent group having an ethylene oxide chain represented by (—O—C R1 represents a group selected from the group consisting of groups represented by the following formulas (2) and (3); L represents polysiloxane having at least a SiO R2 represents a monovalent group selected from the group consisting of monovalent groups represented by the following formulas (4) and (5): wherein, in the formula (2), j represents 1, and k represents 0 or 1; R3 represents a bivalent connecting group; the symbol “*” represents the point of attachment to a silicon atom in the polysiloxane represented by L; and the symbol “***” represents the point of attachment to an oxygen atom in the ethylene oxide chain represented by G, wherein, in the formula (3), p1 and q each independently represent 0 or 1; p2 represents 1; R R the symbol “*” represents the point of attachment to a silicon atom in the polysiloxane represented by L; and the symbol “***” represents the point of attachment to an oxygen atom in the ethylene oxide chain represented by G, wherein, in the formulae (4) and (5), R7, R8, R10, R12 and R14 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, a phenyl group, an alkoxyl group having 1 to 10 carbon atoms, or a phenoxy group; R9, R11 and R13 each represent a bivalent connecting group; the symbol “**” represents the point of attachment to a silicon atom in the polysiloxane represented by L; and X
