Abstract
In local memory that stores image data, the image data is invalidated to prevent leakage of the image data. Input image data is stored in local memoryand subjected to image processing, and then it is saved in a hard disk device. The image data that is read from the hard disk deviceis stored in the local memory, and then printed as an image from a printing portionor transmitted from a communication sectionin data communication. When image data input is completed, image data is left stored in the local memory. Therefore, the image data is overwritten with random data and invalidated so that the image data is unreadable. Also, when image data processing is completed, image data is invalidated.
