ABSTRACT:
An image forming apparatus of the present invention includes: an image carrier on whose surface is formed a latent image; a developing unit that forms a developer image with a developer including toner, carrier and additive; a transfer unit that transfers the developer image onto a recording medium; a recovery member that recovers the developer remaining on the surface of the image carrier after the developer image is transferred; a supply member that supplies, to the image carrier, a recovery promoter; and a voltage application unit that applies, to the supply member, an alternating-current voltage whose amplitude is changed in accordance with a change in the percentages of the amount of toner and the amount of carrier per unit area of a developer image forming portion of the developing unit.
