Embodiment Construction
[0062] Embodiments of a paper folding apparatus, an image forming apparatus, and a paper folding method will be described with reference to the drawings.
[0063] (1) Structure of image forming device and paper folding device
[0064] figure 1 This is an external perspective view of a basic configuration example of the image forming apparatus 10 according to this embodiment. The image forming apparatus 10 includes: a reading section 11 that reads a manuscript, an image forming section 12 that electrophotographically prints image data of the read manuscript on paper, and sorts and punches the printed paper. A paper folding device 20 for post-processing such as processing, folding processing, and intermediate binding processing. In addition, the image forming section 12 includes an operation section 9 for the user to perform various operations.
