<P>PROBLEM TO BE SOLVED: To provide an image forming device solving a problem that sheets are removed from a sheet bundle since an area to be pasted is not sufficiently ensured when the sheet bundle to be bound is thin and further that the non-pasted sheet bundle is bound since a paste vessel is not inserted to a gap and pasting cannot be performed even when the sheet bundle is thick in a sheet treatment device for binding the sheet bundle of the image forming device, and emitting warning when thickness information of the sheet bundle calculated by thickness information calculation means of the sheet bundle is a predetermined amount or less. <P>SOLUTION: The thickness information calculation means for calculating the thickness information of the sheet bundle based on at least one of the number of sheets of the intermediate papers counted by an intermediate paper count means, a paper kind information of a packaging cover and a paper kind information of the intermediate paper is provided. The image forming device for emitting warning when the calculated thickness information is a predetermined amount or less is provided. <P>COPYRIGHT: (C)2007,JPO&INPIT |
