Abstract
In an image forming apparatus, a method of correcting a position for writing an image on a photoconductive element on the basis of a signal representative of a pattern formed on the element and detected, and a device therefor. A single photoconductive element is used to form a plurality of different colored images using a single rotating polygonal mirror and a plurality of light sources. The toner images can be sensed either while they are on the single photoconductive element or by sensing them through a transport belt.
