PROBLEM TO BE SOLVED: To improve throughput in an entire device by adding priority to a process and by efficiently running a plurality of coding means and/or decoding means. SOLUTION: The image-forming device having the plurality of coding means 15 and a plurality of decoding means 16 comprises a process setting means 14-1 for setting a process for performing processing for each coding means 15 and/or for each decoding means 16 and setting the priority of each process for each coding means 15 and/or for each decoding means 16; a process storage means 13 for storing a priority table; an assignment means 14-2 for assigning one or at least two coding means 15 and/or decoding means 16 to one or at least two processes for requesting coding and/or decoding, based on the priority table; and a control means 14-3 for executing the coding or decoding of the process to the assigned coding means 15 or decoding means 16 while parallel processing can be made.
