Abstract
An image forming apparatus includes an image carrier, a developing part that develops an electrostatic latent image formed on the image carrier by using toner, a supply part that supplies a developing bias between the image carrier and the developing part, the developing bias having an AC component superimposed on a DC component, and a setting part that sets a peak-to-peak value of the AC component of the developing bias to vary between a reference value that is determined in advance and a special value smaller than the reference value when an image region on the image carrier passes through a developing region, the image region being a region on the image carrier in which an image is to be formed, the developing region being a region in which the image carrier is opposed to the developing part.
