PROBLEM TO BE SOLVED: To efficiently store the largest number of sheets of paper of different sizes even in the handling of the different paper-sizes in a series of image forming processes by setting the relative number of sheets by the types of sheets of paper, and controlling, according to the set relative number of sheets, the cumulative numbers of sheets of paper stored in a plurality of trays. SOLUTION: Based on paper size information sent as sheets of paper 10 are ejected, a sheet-post-processing control means 40 relatively allocates the number of sheets according to the sizes of the sheets of paper 10 by means of a relative-number-of-sheets processing means 50 and, according to the relative, cumulative number of sheets, it controls the largest number of sheets that each bin stores. That is, in the sheet post-processor 400, the relative number of sheets is set for each sheet of paper 10 based on the information on the size of the sheet of paper 10 ejected from an image forming device main body 100, and cumulates a numeric value for each sheet of paper 10. Based on the cumulative value, the sheet post-processor 400 and the image forming device main body 100 having the sheet post-processor 400 are controlled. |
