SHEET PROCESSING DEVICE AND IMAGE FORMATION SYSTEM

Japanese Patent JP2015013706

A

PROBLEM TO BE SOLVED: To provide a sheet processing device and an image formation system capable of restraining a binding member from being deformed by increasing folding operation, by increasing folding roller pairs, while securing the increasing folding effect.SOLUTION: The sheet processing device comprises: folding means 230 for applying folding processing by sandwiching a sheet bundle with the vicinity of a binding part bound by binding members 50a and 50b of the sheet bundle as a folding position; increasing folding roller pairs 266 for increasingly folding a fold line of the sheet bundle while moving in a sheet width direction by arranging a pair of roller members having a shaft in the orthogonal direction to the sheet width direction so as to sandwich the sheet bundle; and energizing means 265 for imparting energizing force for pressing at least one roller member of the increasing folding roller pairs to the fold line, to the roller members, and comprises: energizing force changing means for changing the energizing force when the binding members pass through a certain part when the increasing folding roller pairs move the fold line in the sheet width direction so as to become weaker than the energizing force just before the increasing folding roller pairs pass through the binding members.
