An object of the present invention is to provide a charging roller cleaning mechanism capable of efficiently removing substances electrostatically attached to the surface of a charging roller and maintaining good cleaning performance for a long period of time. Kind Code: A1 A charging roller cleaning mechanism for cleaning a surface of a charging roller for charging an outer surface of an image bearing member, the charging roller cleaning mechanism comprising at least an elastic layer provided on an outer periphery of a core metal, wherein the thickness of the fiber is 0.1 to 0.1. A conductive brush roller 2b having a denier of 20 denier, a fiber length of 0.3 to 2.5 mm, and a fiber density of 7,000 to 46,000 fibers / cm 2 ; When a bias is applied to the charging roller 2a, the charging roller 2a has a mechanism for setting the same potential as the charging roller 2a.
