Patent abstract
An image density in a predetermined section of an image represented by an image signal is calculated on the basis of the image signal, and the calculated image density is compared with the result of detection of a density in the predetermined section of a toner image formed on the basis of the image signal. Then, it is determined whether or not to perform a density-adjusting process in which an image-density adjustment is performed on the basis of correction pattern data. Thus, the density adjustment is performed at a suitable timing while monitoring the density of images formed in a normal image-forming operation.
