<p><P>PROBLEM TO BE SOLVED: To allow transfer of a toner image onto the back surface of paper, without causing the paper to be conveyed in reverse. <P>SOLUTION: A toner image formation portion 19 forms a main toner image, based on main image data and forms an auxiliary toner image based on auxiliary image data for a rotational photoreceptor 21. A pressing roller 23 is disposed to press the rotational photoreceptor 21 and transfers a toner image to paper conveyed between the rotational photoreceptor 21 and it. A paper conveyance control portion 17 performs conveyance control of the paper, at a predetermined interval for each paper. A printing control portion 27 forms the main toner image on the rotational photoreceptor, based on the main image data for each page. The printing control portion 27 controls the toner image formation portion 19 to form the auxiliary toner image on the rotational photoreceptor, in the front side region from the main toner image formation position for one page, and controls the paper conveyance control portion 17 so that the paper is conveyed at an interval wherein the auxiliary toner image is directly transferred to the pressing roller 23. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
