To provide a charging roller cleaning mechanism of efficiently removing matters to be electrostatically stuck on the surface of an electrifying roller and maintaining a good cleaning performance over a long period.
As for the charging roller cleaning mechanism which is constituted by arranging at least an elastic layer on the outer periphery of a core bar and cleans the surface of the charging roller 2a for charging the surface of an image carrier 1, the cleaning mechanism is provided with a conductive brush roller 2b constituted of fibers of 0.1 to 20 deniers in thickness, 0.3 to 2.5 mm in length, and 7000 to 46000 pieces/cm2 in density, and the conductive brush roller 2b is provided with a mechanism of making the roller 2b have the same potential as that of the charging roller 2a when a bias is applied on the charging roller 2a.
