Abstract:
PURPOSE: To stably keep printing quality and to effectively use developer by displaying for urging the manual adjustment of printing density and performing prescribed adjustment in the case adjustment is not performed when the remaining amount of the developer becomes small. CONSTITUTION: When toner in each developer tank is decreased to a specified amount, a toner sensor 43 detects that, a CPU 46 reads the information through a driver receiver 45, and the CPU 46 informs of that the toner is depleted by displaying a message previously stored at a ROM or a RAM 47 on a display part 49 through a driver 48 as character information or flickering an LED. When a user does not adjust density after the lapse of a fixed period after the display is performed, the potential of laser beams emitted from a laser beam emitting device is controlled based on a specified function, so that exposure to a photoreceptor drum is adjusted and density adjustment is automatically performed.
