ABSTRACT:
It is determined whether management information exists in an erasure folder or not after a power of an image forming apparatus is turned on. When the management information exists, image data is erased based on information of the management information. Then, it is determined whether the power is turned off or not during the erasing operation, and when it is determined that the power is turned off, the erasing operation of the image data is stopped and the management information remains in the erasure folder, but when it is determined that the power is not turned off, the erasing operation of the image data is completed.
