Abstract
A display device in an image forming apparatus includes a liquid crystal display panel. The display panel selectively displays two types of modes, that is, a normal mode and a special mode. In the normal mode, a copy volume, a copying magnification, a copy density and the like are displayed. In the special mode, the contents for setting edit copies, the contents for setting composite copies and the like are displayed. According to the present invention, the special mode is displayed during only a constant time period in a case where each of special mode setting keys is operated. In the other cases, the display mode is automatically switched to the normal mode. More specifically, the normal mode which a user desires to know is usually displayed on the display panel. Only when the user sets the special mode, the special mode is displayed in response to an operation of each of the special mode setting keys. Accordingly, the display device has good operability.
