A picture image forming system has a large and conspicuous display of stapling positions and thereby helps prevent an erroneous stapling position from being selected. The picture image forming system includes a picture image forming system body for forming a picture image on the basis of an inputted picture signal and for reading image data including the orientation and size of an original to be copied, using a picture image reader. The picture image forming system also includes an operating part for displaying a picture image of only one type of original so as to include a vertical or horizontal orientation and for displaying a plurality of selectable stapling positions on the picture image of only one type of original in layers. The operating part reads one or more stapling positions selected from the plurality of selectable stapling positions. The picture image forming system further includes a stapler for binding a plurality of copied sheets on the basis of information about the selected stapling positions.
