## Abstract

A binding device includes a first pushing member that includes protrusions along one direction and that pushes a recording-material bundle as a result of pushing the protrusions against one of surfaces of the recording-material bundle, the protrusions disposed side by side in a direction that intersects the one direction; and a second pushing member that includes protrusions along the one direction and that pushes the recording-material bundle as a result of pushing the protrusions against the other surface of the recording-material bundle, the protrusions disposed side by side in the direction that intersects the one direction, wherein, in at least one end portion in the one direction of each protrusion of at least one of the first pushing member and the second pushing member, a hollow is disposed in a top portion of each protrusion.

## Claims

### Claim 1

A binding device comprising:
a first pushing member that includes a plurality of protrusions along one direction and that pushes a recording-material bundle as a result of pushing the plurality of protrusions against one of surfaces of the recording-material bundle, the plurality of protrusions disposed side by side in a direction that intersects the one direction; and
a second pushing member that includes a plurality of protrusions along the one direction and that pushes the recording-material bundle as a result of pushing the plurality of protrusions against the other surface of the recording-material bundle, the plurality of protrusions disposed side by side in the direction that intersects the one direction,
wherein, in at least one end portion in the one direction of each protrusion of at least one of the first pushing member and the second pushing member, a hollow is disposed in a top portion of each protrusion.

### Claim 2 (depends on 1)

The binding device according to claim 1, wherein the first pushing member and the second pushing member each include a base portion, the protrusions of the first pushing member protruding from a surface of the base portion of the first pushing member, the protrusions of the second pushing member protruding from a surface of the base portion of the second pushing member,
wherein at least one end portion in the one direction of each protrusion of the other of the first pushing member and the second pushing member includes a side wall that is connected to the surface of the base portion thereof, and a portion where the side wall and the surface of the base portion thereof are connected to each other includes an intersecting portion, and
wherein a position in the one direction of the intersecting portion of the other of the first pushing member and the second pushing member and a position in the one direction of a region where the hollow of the one of the first pushing member and the second pushing member is formed are aligned with each other.

### Claim 3 (depends on 1)

The binding device according to claim 1, wherein the first pushing member and the second pushing member each include a base portion and a trough portion, the protrusions of the first pushing member protruding from a surface of the base portion of the first pushing member, the protrusions of the second pushing member protruding from a surface of the base portion of the second pushing member, the trough portion of the first pushing member being provided between the protrusions of the first pushing member that are adjacent to each other, the trough portion of the second pushing member being provided between the protrusions of the second pushing member that are adjacent to each other, and
wherein, in each of the first pushing member and the second pushing member, in a direction in which the protrusions protrude, the surface of the base portion is positioned between the top portions of the protrusions and a bottom of the trough portion.

### Claim 4 (depends on 1)

The binding device according to claim 1, wherein a vertex angle of each protrusion of the at least one of the first pushing member and the second pushing member is less than an opening angle of a trough portion positioned between the protrusions of the other of the first pushing member and the second pushing member.

### Claim 5 (depends on 1)

An image forming system comprising:
an image forming unit that forms images on recording materials; and
the binding device according to claim 1 that binds the plurality of the recording materials on which the images are formed by the image forming unit.
