PROBLEM TO BE SOLVED: To provide an image forming system making the maintenance work simplified by letting one unit of the image forming device maintain the use frequency information in the image forming device. SOLUTION: This image forming system is constituted by image forming devices 1, 2, 3 and 4 being connected thereto. With regard to individual structure of the respective image forming device, for instance, the image forming device 1 consists of the operating part 11, the copying part 12, the net work interphase part 13 and a use summed-up counter part 14. The number of copying sheets processed by the copying part 12 is transmitted to the use accumulation counter part 14 as the copying sheet number information through the net work interphase part 13. The use accumulation counter part 14 makes it possible to simplify the maintenance work by adding and holding the copying sheet number information transmitted through the net work interphase part 13 to the accumulated value maintained at the present time, transmitting the accumulated value to another image forming device, and maintaining after transferring the accumulated value of the number of copying sheets to another image forming device. |
