Abstract:
1. An image forming apparatus comprising: an imaging unit including: a controller, when control target values of control parameters that influence a developing ability of the imaging unit becomes inappropriate, performs target value correction processing of correcting the control target values to bring the control target values close to appropriate values for stabilizing a development density of the imaging unit, wherein, in the target value correction processing, the controller corrects a second 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 response speed of a first control parameter, corrects a first control target value of the first control parameter, and then turns the second control target value of the second control parameter back to an original value of the second control parameter after correcting the first control target value of the first control parameter, and wherein in the target value correction processing, the controller performs processing of returning the second control target value of the second control parameter to the original value of the second control parameter after correcting the first control target value of the first control parameter, and then returning the first control target value of the first control parameter to an original value of the first control parameter before target value correction processing, depending on a state of increasing the frequency of performing the image forming operation in each unit time.
