<p>A registration portion which conveys a sheet toward an image forming portion forming an image on the sheet includes a controlling portion which regulates a sheet skew feeding correction amount by the skew feeding correcting portion based on the sheet right angle degree detected by the end detection sensor. The controlling portion automatically calculates, from the sheet right angle degree detected by the end detection sensor, a skew feeding regulation amount used for making any one of the two sides, forming the corner of the sheet, parallel to the image and corrects the skew feeding of the sheet by the skew feeding correcting portion with the use of the skew feeding regulation amount so that any one of the two sides forming the corner of the sheet is parallel to the image.</p> |
