ABSTRACT:
In the formation of a multicolor image for generating a color print by repeating operation for transferring on an intermediate transfer member every color after one color toner image is formed on a photoreceptor drum, when an image of each color is written on the photoconductor, the image writing start position of each color is differentiated in a process direction of the photoconductor on the basis of a position reference mark on the intermediate transfer member detected by a sensor. This prevents a defect on the photoconductor from being enlarged and visually conspicuous.
