<p>PROBLEM TO BE SOLVED: To provide an image formation device capable of improving an image formation number per unit hour, correcting a skew, and post-processing paper sheets after printing by enlarging intervals of paper sheets as necessary. SOLUTION: Supposing that a paper carrying speed of a regist roller 3 is set to V1, the carrying speed of a paper feed roller is set to V2, a distance from a separation position to a sensor 4 separately feeding paper sheets stacked on a tray one by one is set to L, and a time required for the sensor 4 from detecting the rear end of a first paper sheet 1 to detecting the tip of a second paper sheet 1 is set to T1, a paper feed conveyer is constituted to form L/V2-L /V1>=T1. Assuming that a time longer than T1 is set to T2, this image formation device can select the time T1 or T2, namely, the interval between the rear end of the first paper sheet 1 and the tip of the second paper sheet 1.</p> |
