[Means for solving problems]
The first invention, after the transfer of the first surface of the recording material by the transfer conveying means the image formed by the image forming means, in order to perform image recording on the second surface of the recording medium, wherein the recording material In an image forming apparatus having a re-feeding transfer path for re-feeding the image forming means, the transfer transfer means is used to provide a positioning means for positioning the lateral transfer position of the recording material conveyed through the re-feed transfer transfer path. It is characterized in that it is integrally provided with a frame member that supports.

第2の発明は、第1の発明で、前記再給紙搬送を構成するガイド部材を、前記フレーム部材に一体に設けたことを特徴とする。
The second invention is the first invention, characterized in that the guide member constituting the re-feeding transfer path is integrally provided with the frame member.

給紙カセット8aは複数枚の転写材Sを収納し、装置本体内底部に装填される。給紙カセット8aからの画像形成時には、カセットピックアップローラ8a1によって一枚ずつ転写材Sが分離搬送され、カセット搬送ローラ8a2及びレジストローラ8dによって画像形成部まで搬送される。
The paper feed cassette 8a stores a plurality of transfer materials S and is loaded into the inner bottom of the apparatus main body. When forming an image from the paper feed cassette 8a, the transfer material S is separated and conveyed one by one by the cassette pickup roller 8a1, and is conveyed to the image forming portion by the cassette transfer roller 8a2 and the resist roller 8d.
