In the image forming apparatus 1 configured as described above, the paper stored in the uppermost paper feed cassette 6 among the paper feed cassettes 6... It is assumed that the sheet is not a renewed sheet such as an OHP sheet.
When a copy is made using such special papers, for example, special papers are automatically sent out from a specific paper cassette in accordance with the position of a document set on the document tray 22 of the ADF 20. To make copies. Therefore, when the special papers are set in the paper feed cassette 6, the papers are displayed on the display window 8 and the use of the special paper is displayed on the display label 28 for the document display section 27 of the document tray 22. .

When the special papers are set in the paper feed cassette and the special paper is loaded in the paper feed cassette 6 as shown in FIGS. The special paper is displayed on the document display section 27 of the document tray 22 on the display label 28 thereof. Therefore, when the operator sets a document on the document tray 22,
By checking the display of the document tray, it can be confirmed that a copy using backing paper or the like has been made, and there is no danger of making a wrong copy. If it is conceivable that creation of an erroneous copy is unavoidable only by displaying on both the document tray and the paper feed cassette, the information on the paper set in the paper feed cassette is controlled in addition to the display for each display label. It is possible to add means for inputting the information to the apparatus and displaying the information on another display unit.

For example, as described above, when the special paper is loaded into the paper feed cassette 6, and when the paper feed cassette 6 is loaded into the paper feed section 5 of the image forming apparatus, the set button 9 is pressed and the control unit 30 is pressed. When the information is input to the control device 3,
