Abstract

A charging apparatus for charging a member to be charged includes an elastic member, the elastic member being press-contacted to a surface of the member to be charged, and electroconductive particles carried on the surface of the elastic member to which a charging voltage is applied, wherein a triboelectric charging property of the member to be charged relative to the elastic member is the same as a charging polarity of the charging apparatus.
