Abstract
In an image forming apparatus a developing device develops an electrostatic latent image on an image carrier with a developer that contains toner to obtain a toner image, a toner-amount detecting unit detects amount of toner attached to the toner image, and a toner-density detecting unit detects a density of toner in the developer. Moreover, a process control unit corrects a toner-density target value indicative of a target value of density of toner in the developer based on the amount of toner detected by the toner-amount detecting unit and the density of toner detected by the toner-density detecting unit, and a determines execution timing of next process based on corrected toner-density target value.
