Abstract
A belt cleaning device included in an image forming apparatus for transferring a toner image from an image carrier to a recording medium and conveying the medium while electrostatically retaining it thereon is disclosed. The device allows its belt to be surely cleaned over the entire circumference even when electrostatic cleaning and image transfer share a single power source. The device therefore prevents the rear of the recording medium from being smeared.
