Abstract:
An image-forming apparatus for forming an image on a recording medium includes an image carrier for carrying a toner image corresponding to an image to be formed on the recording medium, a cleaning device including a cleaning member for cleaning the image carrier by removing residual toner remaining on an image-carrying face, and a bias-applying unit for applying a first bias for removing residual toner charged to a first polarity by electrostatic force from the image carrier such that the cleaning member captures residual toner, and expelling the residual toner charged to a second polarity, which is an opposite polarity to the first polarity, by electrostatic force from the cleaning member toward the image carrier, between the image carrier and the cleaning member.
