<p><P>PROBLEM TO BE SOLVED: To provide an image forming device more surely correcting the skew of a sheet. <P>SOLUTION: The image forming device is provided with an after-registration sensor 20 including: a gate 21A swinging and displacing caused by the collision of the tip of the sheet carried out from a pair of registration rollers 17A, 17B; and a sensor 22 detecting the position of the gate 21A. The device is configured so that the gate 21A collides with the sheet in the almost all over the width direction of the sheet carried out from the registration rollers 17A, 17B. This enables the after-registration sensor 20 to obtain the same effect as, so called, skew correction by the registration roller. Accordingly, after the sheet skew is corrected by the pair of the registration rollers 17A, 17B, the sheet skew is corrected again by the after-registration sensor 20, and thereby the sheet skew is more surely corrected. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
