PROBLEM TO BE SOLVED: To prevent the decline of productivity even for the equipment having the composition unable to install a memory of large capacity due to the cost reason in the case of a small-capacity memory like a low-end machine and a full-color machine. SOLUTION: The image formation device which shares the same memory for the one preserving an image data temporarily with an external-input image data inputted from the outside like a scanner, an internal-input image data inputted from the inside like HDD and an external-output image data outputted to the outside like a plotter is provided with a composition enabling two or more internal/external image input controls and an external image output control to be performed simultaneously (parallel operation), thereby executing a memory-sharing, capable of suppressing to the minimum the data input/output between a primary storage and a secondary storage (the primary storage→the secondary storage : image evacuation, the secondary storage→the primary storage : image return or image concentration) for processing two or more input/output image data and of inhibiting the decline of total productivity to the minimum.
