    摘要： An image forming apparatus and an image forming method capable of executing process control at appropriate timing are provided. A control section of an image forming apparatus carries out control for determining execution time of process control and executing the process control. The control section includes a counting section, a determining section and a process control management section. The counting section counts a number of printed sheets. The determining section determines on what time process control is to be executed form the counted number of printed sheets for each time zone. The process control management section manages the process control executed at an image forming section with the whole of the image forming apparatus.

    摘要： A digital color copier includes: a toner concentration storage which, as to a multiple number of developer blocks into which the developer that circulates in the developer device is virtually divided across the image forming width, stores the detected toner concentration of each developer block, detected by the toner concentration detector, separately for every developer block; a toner consumption predictor for predicting the first predicted toner consumption of the toner that is expected to be consumed and/or was consumed from the developer of every developer block during the first circulation, based on the developer's speed of conveyance in the developing device and the print processing speed; a toner concentration estimator for estimating, for every developer block, the toner supply point estimate as the toner concentration at the point where toner is supplied, by subtracting the first predicted toner consumption from the associated detected toner concentration and setting up a toner supply target value of the toner to be supplied from the toner supply device to the developing device in accordance with the predicted toner consumption during the second circulation of the developer inside the developing device that follows the first circulation.

    摘要： It is judged whether a sufficient time for executing all of three correction processings (a high density correction processing, a halftone correction processing, and a registration correction processing) can be secured or not. When the sufficient time cannot be secured, the high density correction processing as an essential correction processing is executed. A history of the halftone correction processing and a history of the registration correction processing are compared with each other. A date of latest execution of the halftone correction processing and a date of latest execution of the registration correction processing are compared with each other to judge whether or not the execution of the halftone correction processing is earlier, and the registration correction processing and the halftone correction processing are executed, respectively.
