Abstract: An image forming apparatus includes a first storage medium to store a storage target file, without storing storage management information of the storage target filed. The image forming apparatus may also have a controller to control storing the storage management information of the storage target file separately from the storage target file. Therefore, without the storage management information that is indispensable for accessing the storage target file the file is secure regardless of detaching the first storage medium from the image forming apparatus.

Abstract: Disclosed is an image forming system comprising a first device and a second device connected to a network, and having an output permission and result notification function for image data stored in the first device. The system comprises a control unit for transferring a request for approval of the first device to the second device and transferring to the first device a response of the second device to the request for approval, and transforming the image data into a printable format and outputting the transformed image data. The request of approval requests an approval of the second device for printing of the image data. The image data is transferred to the control unit from the first device in response to an output permission in the response of the second device. The system comprises a printing unit for printing on a print paper an image corresponding to the transformed image data.
