摘要： An image output apparatus capable of controlling the image density for a specific level in a short time and with accuracy and no control failure. When the values of manipulated variables that are control parameters of the output image quality or a controlled variable are calculated and the parameter values become out of the practically settable range in the course of obtaining new manipulated variables adjusted for controlling the output image quality for a specific level, the image density control unit of the image output apparatus corrects the data in the image density database that are used for comparison in obtaining the parameter values according to the current environmental state and repeats the calculation, whereby no control failure occurs and optimum parameter values are obtained; consequently, the output image quality can be controlled for a target level in a stable manner.
