Abstract
There is provided an image forming apparatus including: a forming section having an image holding member and an developing portion, and configured to apply a developing bias voltage to the developing portion to develop an electrostatic latent image on the image holding member; a sensor configured to detect a mark formed by the forming section; a storage; and a controller configured to perform: forming first and second marks, obtaining the densities of the first and second marks, obtaining a slope, and determining a target bias voltage value, and storing the target bias voltage value in the storage.
