A post-processing device includes a pair of rollers, each arranged such that an axis direction thereof is perpendicular to a transport direction of recording sheets, that forms a fold in the axis direction at a predetermined portion of both surfaces of each recording sheet, a first plate-like member, arranged opposite the pair of rollers, that moves between a feeding position allowing the predetermined portion of each recording sheet to be pinched with a nip portion of the pair of rollers and a standby position being distant from the nip portion, a transport processing unit that causes the recording sheets to be sequentially transported such that the predetermined portion of each recording sheet intervenes between the first plate-like member and the pair of rollers and to be folded by the pair of rollers, and a post-processing unit bundles the recording sheets on each of which the fold has been formed.
