A sheet folding apparatus includes a conveyor, a first folding roller, a second folding roller, a third folding roller, a guide, a motor, and a driving force transmission mechanism. The motor causes the second folding roller to perform either forward rotation in which the second folding roller rotates to convey a sheet on a main conveying path in a conveying direction and to convey the sheet on a reflux conveying path from a joining position toward a branching position or backward rotation in a direction opposite to the forward rotation. The driving force transmission mechanism rotates the guide toward a first posture from a second posture in conjunction with the forward rotation of the second folding roller and rotates the guide from the first posture toward the second posture in conjunction with the backward rotation of the second folding roller.

An enclosing device includes an envelope conveyance path, an envelope loader, an envelope-position restrictor, and an envelope-position adjuster. The envelope conveyance path conveys an envelope to an enclosing position at which an enclosure is enclosed into the envelope. The envelope loader loads the envelope to be supplied to the envelope conveyance path. The envelope-position restrictor restricts a loaded position of the envelope in the envelope loader. The envelope-position adjuster adjusts a position of the envelope with respect to a conveyance direction of the envelope while maintaining a state in which the envelope-position restrictor restricts the loaded position of the envelope.

A liquid application device for applying liquid to a plurality of media to be crimped by a crimping device includes a liquid applier and a liquid-applier moving mechanism. The liquid applier applies liquid to the plurality of media. The liquid-applier moving mechanism moves the liquid applier to a first position at which the liquid applier applies liquid to a medium on a conveyance path in the liquid application device and a second position at which the liquid applier applies liquid to the plurality of media inserted through a liquid application slit of the liquid application device.

A sheet folder includes a conveyor conveying a sheet, a first folding roller and a second folding roller that form a first nip, a third folding roller forming a second nip with the second folding roller, a first guide movable between a first guide posture and a first retracted posture, a second guide movable between a second guide posture and a second retracted posture, and a motor. The motor rotates the second folding roller forward to convey the sheet toward the first nip, reverse to convey the sheet toward the second nip, moves the first guide to arrange in the first guide in the first guide posture or the first retracted posture, and moves the second guide to arrange the second guide in the second guide posture or the second retracted posture.

A medium processing apparatus for processing a medium ejected from an image forming apparatus includes a conveyor, a slit, a medium processing device, a stopper, and detectors. The conveyor conveys the medium ejected from the image forming apparatus. The slit communicates with an opening of a housing into which a medium is manually inserted from outside and includes a placement face on which the inserted medium is placed. The placement face has a first side and a second side orthogonal to the first side. The first and second sides are not parallel to a direction in which a side face of the housing extends. The medium processing device processes the medium conveyed by the conveyor or the medium placed on the slit. The stopper regulates edges of the medium along the first and second sides of the placement face. The detectors are disposed on the stopper to detect the medium.
