Abstract:
The present invention provides a charging member which can maintain excellent wear resistance even though being used repeatedly. In the charging member having a surface layer, the surface layer is a surface layer constituted by at least one selected from silsesquioxanes having structures represented by a compound (1), a compound (2), a compound (3), a compound (4), a compound (5) and a compound (6), and a polysiloxane having a first unit represented by SiO0.5R1(OR2)(OR3), a second unit represented by SiO1.0R4(OR5) and a third unit represented by SiO1.5R6, wherein the silsesquioxane is contained in the polysiloxane.
