Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image forming system eliminating a defective color shade, of an image obtained by superposing an image obtained using a pressplate and an image using no pressplate, caused by a change with the lapse of time. SOLUTION: An offset rotary press 16 and an electrophotographic device 20 are controlled to print the first superposing image and the second superposing image, the first camera 44A and the second camera 44B are controlled thereafter to pick up the first superposing image and the second superposing image, and the offset rotary press 16 and the electrophotographic device 20 are controlled to print the third density of image by the offset rotary press 16, and to print an image of density added with the fourth density obtained by subtracting the density of the second superposing image picked up by the second camera 44B, from the first image picked up by the first camera 44A, by the electrophotographic device 20.
