Abstract:
An image forming apparatus for forming an image which has a predetermined target density, comprising:image forming means for forming the image; density detecting means for detecting an image density of the image which is formed by said image forming means; and control means having a plurality of processing modes, which are different from each other, for calculating at least one density controlling factor, said control means selectively executing one of said plurality of processing modes in accordance with an operation status of said apparatus, each of said plurality of processing modes being a mode in which a plurality of patch images are formed by said image forming means while changing said at least one density controlling factor, which influences the image density of the image, and an optimal value of said at least one density controlling factor, which is necessary to adjust the image density of the image to the target density, is determined based on the densities of said patch images.
