Document Type and Number:
Japanese Patent JP2015212178
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sheet processing device and an image forming apparatus, which perform folding processing and binding processing for a sheet in an excellently apparent state.SOLUTION: A processing roller pair 59 (conveyance roller pair) is configured such that a first outer circumferential part 59a which rimples a sheet P while nipping the sheet P with a nipping part so as to fold the sheet P is formed on a part of a rotation direction, a second outer circumferential part 59b which forms ruggedness in the thickness direction on an edge part in a width direction of the sheet P subjected to folding processing by the first outer circumferential part 59a and performs binding processing and a third outer circumferential part 59c which forms ruggedness over a width direction of sheet P subjected to folding processing by the first outer circumferential part 59a and performs binding processing are formed respectively on a part of rotation direction different from the first outer circumferential part 59a and are constituted attachably and detachably by a cam and a tensile spring (attachable and detachable means).
