ABSTRACT:
A sheet processing apparatus configured to bind a sheet bundle includes a folding portion configured to fold the sheet bundle, a sheet processing portion provided upstream of the folding portion and configured to form a groove at a fold position of at least one sheet of the sheet bundle, and a controller configured to control an operation of the sheet processing portion. The controller controls an operation of the sheet processing portion such that a width of a groove formed on a sheet located on an outer side of the folded sheet bundle is larger than that of a groove formed on a sheet located on an inner side of the folded sheet bundle.
