An image forming apparatus includes a controller and an imaging unit having a developing device to develop a latent image on a surface of a latent image carrier with toner. When control target value of control parameters that influence a developing ability of the imaging unit becomes inappropriate, the controller performs target value correction processing of correcting the control target value to bring the control target value close to an appropriate value for stabilizing a development density of the imaging unit. In the target value correction processing, the controller corrects a control target value of a second control parameter having a response speed, obtained when the developing ability is changed by the correction, faster than a first control parameter, correct the control target value of the first control parameter, and then turn the control target value of the second control parameter back to the original value. |
