In order to miniaturize an image forming system, the present invention provides an image forming system which is provided with a sheet feed apparatus including a transport roller pair capable of transporting a sheet in a sheet transport direction S, and an image forming apparatus including an image forming section capable of forming an image on the sheet acquired from the sheet feed apparatus, including a switch member disposed on the downstream side of the transport roller pair in the sheet transport direction to be switched between a first position for guiding the sheet transported by the transport roller pair to the image forming apparatus, and a second position for guiding the sheet transported by the transport roller pair downward, and a storage tray disposed below the switch member predetermined space apart to be able to store the sheet guided to below the switch member positioned in the second position.

Image forming system

A sheet folding apparatus includes: a conveying roller conveying a sheet in a predetermined conveying direction; a folding roller pair disposed downstream of the conveying roller in the conveying direction and rotating while nipping a predetermined position of the sheet to form a fold; a conveying path for conveying the sheet in the conveying direction from the conveying roller to the folding roller pair; an abutting member moving downstream in the conveying direction and abutting against the predetermined position of the sheet to bend the sheet downstream; and a loop space where the sheet is bent between the conveying roller and folding roller pair in a direction crossing the conveying direction. The folding roller pair stops while nipping a front end of the sheet fed from to form a loop of the sheet in the loop space, and the abutting member moves to abut against the loop.

Sheet folding apparatus and image forming system having the same

The present invention is to provide an image forming system including a sheet folding processing apparatus and a sheet pressing apparatus capable of performing additional folding processing without decreasing productivity. The sheet pressing apparatus of the present invention includes a pressing roller including a pressing surface configured to press a fold line part of a folding processed sheet conveyed from a carry-in port in a thickness direction of the sheet and a guide portion configured to guide the folding processed sheet so that the fold line part is positioned at the pressing surface, a nipping member configured to nip the fold line part between the pressing surface and the nipping member, a first moving unit configured to move the pressing roller to a nipping position at which the fold line part is nipped between the nipping member and the pressing surface of the pressing roller and a retracting position.

Sheet pressing apparatus and image forming system including the same

In a sheet folding apparatus for folding a sheet, a sheet is pushed at a predetermined position thereof by a push member while the sheet is being conveyed by a conveyance roller. The predetermined position of the sheet is guided to the nip section of a folding roller pair. Then, the sheet is nipped at the predetermined position thereof and folded by the folding roller pair.

Sheet folding apparatus

Provided is a sheet folding apparatus for folding sheets, including: a feeding-roller pair; a loop-forming space provided downstream from the feeding-roller pair, for forming a sheet loop; a pushing member for pushing the looped sheet; a folding-roller pair for nipping a prescribed part of the sheet pushed by the pushing member, thereby to fold the sheet; and a path provided between the feeding-roller pair and the folding-roller pair, for guiding the sheet fed from the feeding-roller pair toward the loop-forming space.
