PURPOSE: To prevent inconvenience due to incorrect paper feed while both-face recording of recording information of consecutive multi-page is performed in a recording controller supplying the recording information to a double-sided recording means alternately performing a first surface recording for an M+i-th recording sheet (i is a natural number successively increasing) and a second surface recording for the i-th recording sheet after the first surface recording of first to M-th recording sheets (M is a natural number, and is a fixed value) are performed. CONSTITUTION: A one side surface printed sheet paper whose front/rear side is turned over by an inversion mechanism 1-10 is sent to a pre-transfer transfer path 1-2 through a post-inversion transfer path 1-11, and the image transfer of the rear surface (the second surface) is performed similarly to the time when the one side surface is printed previously by a drum 1-3 and a transfer electrifier 1-4. Thereafter, the sheet paper is sent to a fixing device 1-6 through a before fixing transfer path 1-5, and the image fixing of the second surface is performed in the device 1-6. At the point of time, the double-sided print is finished. |
