PROBLEM TO BE SOLVED: To prevent a sheet from being discharged to a fully loaded bin, even when image forming is started before an actual loading amount of a selected paper discharge bin can be detected, generated in a constitution detecting the loaded amount of a plurality of paper discharge bins by a single sensor. SOLUTION: In an image forming device 102 having a plurality of paper discharge bins 251 to 253 storing paper formed with an image to switch a paper discharge destination by a bin lift motor 260, a paper discharge loading amount detection sensor 261 detecting a loading amount of the paper discharge bin able to discharge paper is provided, in the case of changing of the paper discharge bin, the paper discharge bin 251 to 253 is moved by the bin lift motor 260, a loading amount of the paper discharge bin made able to discharge paper after movement is detected in the paper discharge loading amount detection sensor 261, thereafter starting of image forming is indicated. |
