The transfer paper is reversely fed from a paper feed path 15B installed in the space between a transfer section and a paper feed cassette 15 via a paper feed path 15A, it is inverted upside down and again fed to the transfer section, the toner image is transferred on the back face, and the image on the back face is fixed by the fixing device 17 returned to the pressing state in the rotating direction. |
