A binding device having a binding member that operates at a binding position of objects to be bound has a structure with which the bound objects do not readily come off. The binding device includes a board having a bearing plate. A spring member and an operation lever are attached to a shaft inserted in the bearing plate and a turned-up part. Protruding pieces of a binding member are inserted in through holes of turned-up parts formed in the board. One end of the spring member is secured to the operation lever, and the other end is fitted in a through hole of a turned portion at the distal end of the binding member. By closing the operation lever, the binding member rotates around a line connecting the protruding pieces at both ends, thereby pressing down sheets of paper placed on the board with a pressing portion. At this time, the other end of the spring member presses the turned portion, thereby biasing the pressing portion.
