摘要：The present invention aims to achieve compatibility between high conductivityand durability against the application of a DC voltage in the charging member of anelectrophotographic apparatus for maintaining the image quality of theelectrophotographic apparatus in association with an increase in speed of the
electrophotographic apparatus and more severe use conditions thereof in recent years.Provided is a charging member having a conductive support and a conductive elasticlayer, in which: the elastic layer contains a polymer having an alkylene oxide chain in amolecule thereof, an ion conductive agent, and a polyrotaxane; and the polyrotaxane hasa structure in which a linear molecule penetrates the inside of the ring of a cyclicmolecule having an ionic group, the linear molecule has two block groups, and the blockgroups are placed at both terminals of the linear molecule to prevent the cyclic moleculefrom leaving the linear molecule.
