Abstract
A binding member includes: an upper tooth that has an upper tooth form for forming unevenness in a bundle of recording materials; and a lower tooth that has a lower tooth form for forming unevenness in the bundle of recording materials and that forms a pair with the upper tooth. At least one of the upper tooth form and the lower tooth form is formed such that, in a sectional shape, a groove is formed in a trough portion of a concave portion of a tooth form and a length of an inclined portion which comes into contact with the bundle of recording materials is made small compared to a case where the inclined portion of the tooth form has reached a bottom of the trough portion.
