And the ID the same (S76: Otherwise), and digital multifunctional device forbids to coding (S86), a display on the operating unit 107 display panel indication according to forbids decrypting the (S88) and method for loop. The circumstances an, image forming a self-encrypted image is used for out through the original design, or a forbid image forming itself. And the operating content of reading excluding is permitted to person's ID of the encrypted image for coding (S72: Otherwise), or outside ID with is permitted same to person's ID of the encrypted image for coding (S76: Is), a flow according to compromised shown the digital of 4 to the first embodiment, the digital multifunctional device associated the decoding of encryption image (S78), and a deciphered the original image of the image reading unit 101 readings' encryption time of the memory reading unit 110 readings' keys (S80), dealt with a basing on the image information to the image information of coding and image on the paper (S82) and method for loop. Therefore, the person of the outer through forbidding of assigning device of the coding to the encrypted image, capable of preventing the information the leakage. According to image forming apparatus of the present invention, and forbid the encrypting the other image forming apparatus copy original image information of processor, preventing the information the leakage. And; and after deciphers and easily, and one, and a transmission the key of the image information of image forming device encryption. According to image forming apparatus of the present invention, and related information storage of image in memory. Is connected to the memory reading image information related and a display. , And capable of preventing to the self-encrypted image is deciphered and printing layer of the misoperation. According to image forming apparatus of the present invention, and is arranged on the coding to the encrypted image from the storage, the reading forming images times of display and times, tube and printing the paper. According to image forming apparatus of the present invention, capable of with the image decoding of form a digital on the paper are, wherein indication through for coding to form the image to the encrypted the times, so is a to this indication to form an image the time sequence of. A clock, indicating device and image display the time sequence is a image of non-interference coding to form. According to image forming apparatus of the present invention, and forbid the first times or more times of forming the image with the decoding of encryption image. Is further arranged forbid to form an image with the image coding and predetermined. Is a assigning connected on the side forbids to coding, wherein the work and information a longer necessity preventing the coding and printing of image. According to image forming apparatus of the present invention, and a through for coding to form the image decoding to the encrypted image image forming apparatus. Energy - limit is used is placed on the password of people to the encrypted the coding and decoding the image (password). Are separated from the invention mental and base the condition, the multiple and implement the invention, therefore the embodiment is declarative, and a restrictive layer, the invention's range is formed with a use of ion beam, the non-front indication foldable define the invention claims a into wherein the fully the waterproof or the periphery of the wavelength of the equivalent invention is further cover by use of ion beam.
