<p>PROBLEM TO BE SOLVED: To execute a recording action at a high speed by executing a driving control action utilizing both of the normal and the reverse rotation of a motor. SOLUTION: A paper supply roller 12 is rotated by the normal rotation of the motor so as to feed a paper to a section A. Then, a standby sensor 17 is turned in a carrying direction by the leading edge of the paper. Besides, the leading edge of the paper abuts on the interposing part of a stopped standby roll pair 18 and it is stopped. The rotation of the roller 12 recognizing the turning action of the sensor 17 is stopped. Next, while the paper is carried in a section B by the reverse rotation of the motor, the simultaneous exposure and developing action of a back surface is executed on a transparent photoreceptor 28. Then, the toner image thereof is adhesively transferred on an intermediate transfer belt 26 and carried to a faced surface between a transfer roller 21 and a heating roller 22. Besides, it is transferred and fixed on the surface of the paper. The printed paper is stopped in a section C. The next(following) paper is carried again to the section A by the normal rotation of the motor and the above mentioned simultaneous exposure and developing action of the back surface and the transfer and fixing action of the toner image are executed again on the following paper by the reverse rotation of the motor. Simultaneously, the former paper in the section C is ejected.</p> |
