Abstract
A sheet processing apparatus includes a folding apparatus which folds a sheet bundle, a switching portion which switches a nipping pressure of the folding apparatus against the sheet bundle, and a flattening apparatus which presses and flattens a folded-back portion of the folded sheet bundle. The switching portion operates such that the nipping pressure of the folding apparatus against the sheet bundle when the flattening processing is executed becomes weaker than that of the folding apparatus when the flattening processing is not executed.
