The invention relates to an image formation device and an image information saving method, which can reduce theimage variation during the use of boxes as well as re-editing constraints. An image reading unit reads an image from a document to generate base image data. A control unit determines the reading condition setting prescribed by users during the image reading. An information saving unit saves the base image data and the reading condition settings (editting information) in association with each other as saved-image information. Also, the control unit determines output condition settingswhen the images are prescribed to output during the output of the base image data. In addition, the control unit determines the editting contents based on the reading condition settings and the output condition settings of the base image data. An image editing unit uses the determined editting contents to edit the base image data and output the image data. The control unit outputs the image data to a printing unit or a communication unit.
