Stapler

A stapler comprising:

• a striking part configured to cause a pair of staple legs to penetrate a sheet bundle;
• a bending part configured to bend the staple legs at a first position such that tips of the staple legs having penetrated the sheet bundle by the striking part are directed inwardly;
• and
• a clincher part configured to bend the staple legs at a second position located closer to the sheet bundle than the first position such that the staple legs of which the tips are bent inwardly at the first position by the bending part are entirely directed inwardly,
• wherein the bending part includes:
• a first part disposed on an inner side of the pair of staple legs and having a first tip portion facing the staple legs and located at the first position;
• a second part disposed on an outer side of the pair of staple legs and having a second tip portion facing the staple legs and located on a non-sheet bundle side spaced from the sheet bundle farther than the first position;
• and
• a moving part configured to move at least one of the first part and the second part toward the staple legs,
• wherein the first part further includes a first operated portion that protrudes on the non-sheet bundle side farther than the first tip portion such that the first operated portion is above the first tip portion, and
• wherein the first tip portion protrudes toward the staple legs farther than the first operated portion.
