摘要：
A sheet binding unit includes a first sheet binder having first and second dentate uneven sheet binding elements to conduct a first sheet binding process by engaging each other by a prescribed meshing depth while sandwiching the sheet bundle therebetween to form a dentate unevenness on the sheet bundle at a first sheet binding portion of the sheet bundle, and a second sheet binder having third and fourth dentate uneven sheet binding elements to conduct a second sheet binding process by engaging each other by a greater meshing depth than that made by first and second dentate uneven sheet binding elements of the first sheet binder while sandwiching the sheet bundle therebetween to form a dentate unevenness on the sheet bundle at a second sheet binding portion different from the first sheet binding portion of the sheet bundle.
