Abstract
An image forming apparatus includes an image carrier that rotates, a latent image forming unit that forms an electrostatic latent image on the image carrier, a developing unit that develops the electrostatic latent image formed on the image carrier, with a developer including a toner and an external additive, a transfer unit that transfers an image developed on the image carrier to a recording material, a cleaning member that cleans a residue remaining on the image carrier after transfer, a supply unit that supplies a developing bias, which has an alternating-current component superimposed on a direct-current component, between the image carrier and the developing unit, and a setting part that increases a peak-to-peak value of the alternating-current component of the developing bias when a non-image region on the image carrier passes a developing region, in comparison to when an image region on the image carrier passes the developing region.
