ABSTRACT:
A cleaning apparatus for a rotatable brush that contacts upon or slides along a carrier of electrostatic latent images in order to apply an electric potential to the carrier of the electrostatic latent images, includes, an elastic foam body pressed by the bristles of the rotating brush provided downstream in a direction of a rotation of the rotating brush from a position of contact with the carrier of the electrostatic latent images, and a slide member pressed by the bristles of the rotating brush downstream in the direction of the rotation of the rotating brush from the elastic foam body, wherein the elastic foam body has a contact face that presses the rotatable brush, a discharge face that discharges developer or the like that enters the elastic foam body, and all faces other than the contact face and the discharge face are sealed.
