Abstract
A CPUexecutes a control program stored in a memorythereby forming a plurality of patch images with a developing bias increased for each of the patch images; detecting a density of each of the patch images by means of a patch sensor; and comparing the image densities to determine whether the image density is saturated or not. Then, an image forming condition in which an image density is substantially saturated is determined and is stored in the memory. When a print command signal is inputted from an external device via a main controller, a printing operation is performed under the image forming condition stored in the memory
