PROBLEM TO BE SOLVED: To provide an image forming device capable of stably correcting a curl with a simple structure and at low cost. SOLUTION: The image forming device capable of double-sided copying is equipped with a curved carrying path part and a carrying roller pairs. The curved carrying path part is installed at the downstream side of the carrying direction of a fixing roller on an automatic reversal carrying path and carries and guides a transfer paper curving the surface of the transfer paper contacting with a heating roller to be the inner wall outside. The carrying roller pairs are installed at the downstream side of the carrying direction of the transfer paper from the curved carrying path part on the automatic reversal carrying path, and consists of a soft roller press-contacting to the back surface of the transfer paper and a hard roller press-contacting to the front surface of the transfer paper and corrects the curl of at least one transfer paper. A circular nip part is formed by press-contacting the soft roller with the hard roller and corrects the curl of the transfer paper in the middle of carrying/holding the transfer paper.
