PURPOSE:To unnecessitate exclusive space for an exclusive density display device or a density setting lever, etc., by providing more than one density setting keys, which set the image density of the copying machine and a display device, which can replace more than two condition displays according to the input of a density setting key. CONSTITUTION:The image density is set by more than one density setting keys 5 and 6, and either condition display of copying number setting or image density setting is replaced according to the input of the density setting keys 5 and 6. The display device 4a is replaced from the first condition display to the second condition display, when there is no operation after a specified time, is returned from the second condition display to the first condition display automatically, and can be shared as the displayer for the first condition display and the second condition display. Further the display device 4a can be shared as copying number setting displayer and as the image density setting display device by being replace as each condition display of copying number setting and the image density setting. Thus, the exclusive space for exclusive density display device or the exclusive density setting lever, etc., becomes unnecessary. |
