IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image forming device capable of gluing bookbinding causing no positional dislocation of a transfer material by a curl and the extension-contraction and no waviness of the transfer material and capable of bookbinding at mixedly printing time of one surface and both surfaces. SOLUTION: This image forming device is characterized by performing bookbinding by continuously performing a process of performing gluing on an end part of the transfer material by a gluing bookbinding device after heating and fixing a toner image of both surfaces of the transfer material by a fixing means comprising a pair of roller-shaped fixing members by transferring the toner image formed on an image carrier to both surfaces of the transfer material via an intermediate transfer body.
