Abstract
A pair of registration rollers are provided upstream in a paper transport path from an image forming position, and a paper transport position detection portion is provided upstream in the paper transport path from the pair of registration rollers. When consecutive print processing on a plurality of sheets of paper is performed, a paper transport position in the paper transport path is detected by the paper transport position detection portion for a sheet of paper that has been set in advance among the plurality of sheets of paper. A correction amount of a position for image writing to a photosensitive drum is determined based on the paper transport position, and correction of the image writing position is performed based on the correction amount. Image forming on the sheet of paper is performed at the image forming position based on the image writing position after correction, and image forming on other sheets of paper after the sheet of paper that was set in advance is performed at the image forming position based on the image writing position after correction.
