a stacking portion on which sheets are stacked;
a binding unit which binds the sheets stacked on said stacking portion into a sheet bundle; and
a plurality of conveying portions, arranged along a sheet conveying direction for independent movement toward and away from

of said plurality of conveying portions nearest to a bound portion of the sheet bundle bound by said binding unit and located
on a downstream side of the bound portion with respect to the sheet conveying direction is spaced apart from the sheet bundle
before the bound portion passes said one conveying portion, and another conveying portion located more downstream than said
one conveying portion with respect to the sheet conveying direction conveys the sheet bundle, and
