The current methods and systems for cleaning residual ultra-fine spherical toner from an image forming surface discloses the application of aspherical toner to a cleaning blade. The aspherical toner is generally larger than the ultra-fine spherical toner which provides a superior image on an image-carrying medium. According to one preferred embodiment of the current invention, the aspherical black toner is placed in a predetermined area outside of a desired image area where the ultra-fine spherical toner in multiple colors is placed. The aspherical toner is transported to the cleaning blade before the multi-color toner reaches the cleaning blade. Since the aspherical toner applied at a contacting edge of the cleaning blade provide an effective seal or trap between the cleaning blade and the image forming surface, the ultra-fine spherical toner is effectively removed from the image forming surface.
