<p><P>PROBLEM TO BE SOLVED: To improve both-sided productivity by reducing time needed for paper inversion and to steadily convey paper by preventing a jam. <P>SOLUTION: In the image forming apparatus, a main CPU 100 is designed so that hold time h is longer than time t1+t2 which is needed to increase or decrease speed only with a pair of ejection rollers 70 in order to improve the productivity of both-sided printing, waiting till the timing of the secure switching of an inverting gate 90 is ensured, and an amount of movement of paper is, therefore, minimized. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
