An electric stapler is configured to perform communication with a sheet processing apparatus. The electric stapler includes: a binding unit configured to execute binding processing for a sheet bundle; a motor configured to drive the binding unit; a control unit configured to control the motor; and a communication interface configured to perform communication with the sheet processing apparatus. The control unit controls the motor to execute the binding processing by the binding unit when a predetermined signal is received from the sheet processing apparatus via the communication interface.

A stapler includes a staple striking portion configured to strike a staple to penetrate sheets of paper and a clincher portion configured to bend staple legs of the staple penetrating the sheets of paper. The clincher portion includes a pair of clinchers. The pair of clinchers are configured to perform a first operation and a second operation. In the first operation, the pair of the clinchers move along a surface direction of the sheets of paper to approach each other. In the second operation, the pair of clinchers move to approach the sheets of paper after the first operation.

Provided is a stapler device installed to staple a bundle of papers processed and discharged from an image forming apparatus or a post-processing apparatus. The stapler device includes a stapler, and a moving unit installed to allow the stapler to reciprocate in a direction intersecting with a discharge direction of the bundle of papers. The moving unit may rotate the stapler outwardly such that a bundle of papers inserted from the outside in addition to the discharged bundle of papers is stapled in at least one end position of a range of the reciprocating movement.
