BINDING DEVICE AND IMAGE FORMING APPARATUS

Document Type and Number:

Japanese Patent JP2016037379

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a binding device that, even when performing a sheet-bundle binding process by bringing two rotary members, each including a tooth shaped serrated portion formed on its outer circumferential surface of the rotary member, into engagement with each other with a sheet bundle pinched therebetween, is less likely to cause a problem that sheets of the sheet bundle become untidy and are bound unfavorably in terms of appearance, and an image forming apparatus including the binding device.SOLUTION: When the binding process is performed on the sheet bundle PT pinched at an engaging position of the two rotary members 92 and 93 and being relatively moved in a moving direction, a clamping member 94 clamps the sheet bundle PT at a position upstream to the engaging position in the moving direction so as to apply a predetermined pulling force F1 acting in a direction opposite to the moving direction with respect to the sheet bundle PT.SELECTED DRAWING: Figure 3
