If density control is executed during continuous printing, not only the throughput of the interrupted job decreases, but also the density difference between images output before and after the printing interruption may become visually conspicuous. In this invention, a command and a status are exchanged with an external device, and the density of the visible image formed by an image forming section is controlled in accordance with a predetermined command received. When the number of visible images formed by the forming section reaches the first predetermined number, a status instructing execution of density control is transmitted to the external device. When no density control is executed upon transmission of the status instructing execution of the density control and the number of visible images formed by the forming section reaches the second predetermined number, density control is executed regardless of the predetermined command.
