Writing control method and image forming apparatus.

摘要

An image forming apparatus includes: a writing device for writing an image on the basis of image data thereof; a controller for controlling a writing position in a primary scanning direction by the writing device; a conveying device for conveying a recording material; and a position detecting sensor for detecting an edge of the recording material, which is conveyed by the conveying device in the primary scanning direction as an absolute position. The controller determines the writing position in the primary scanning direction by the writing device on the basis of a position of the edge of the recording material in the primary scanning direction detected by the position detecting sensor, and controls the writing position of the writing device in the primary scanning direction. <IMAGE>
