Abstract

An image forming apparatus includes a scanner for scanning an image on a document, a memory for storing image data of the scanned image in a storage medium, a reading device for reading out the image data from the storage medium, and an image forming device for forming an image on an image formation medium. An instruction device instructs a time at which the edit process of the image data scanned by the scanner is executed, according to the content of a designated edit process. On the basis of the instruction, the edit process is executed when the image is stored in the storage medium, or when the image formation is performed by the image forming device. For example, the time at which the edit process is executed is determined in accordance with the possibility of a variable magnification process at a time of output based on the designated edit process and a variable magnification ratio designated by a designation device.
