Abstract
The image forming apparatus controls each laser scanner by setting the writing start timing in the sub-scanning direction to form the color registration correction image for correcting color registration at position according to the detection result of the image detection sensor. When forming the image on the sheet, the image forming apparatus sets the writing start timing in the sub-scanning direction according to the detection result of the image detection sensor and the amount of skew of the sheet to control each laser scanner. When forming the density detection toner image for correcting the density, the image forming apparatus sets the writing start timing in the sub-scanning direction to form the image at a position shifted by a pixel unit from the image forming position on the sheet.
