ABSTRACT:
An image forming apparatus comprises a copy number setting button for setting the number of copies, magnification setting button for setting the magnification, first storing memory for storing the set number of copies, second storing memory for storing the set magnification, a single display for selectively displaying the set number of copies and the set magnification, a display mode switching key for switching the display mode to the copy number display mode or the magnification display mode, and display mode control for switching the display mode on the basis of input by the above display mode switching key. There is also provided a clear key for clearing the set contents and clear control for clearing the set contents of the display mode currently set out of the copy number display mode and the magnification display mode when key input is provided by the above clear key. When key input is provided by the clear key, only the set contents of the display mode currently set out of the copy number display mode and the magnification display mode are cleared. Consequently, it is possible to clear only one of the number of copies and the magnification which is erroneously set. Therefore, the operation efficiency for setting the number of copies and the magnification is increased.
