ABSTRACT:
In order to expose a required exposed line for which an exposing deviation caused by a fixing accuracy of an exposing head is corrected, when exposing images by dynamic lighting control, an image forming apparatus comprises a exposing head24having a plurality of arrayed illuminants aligned in the main scanning direction wherein, when an image bearing body moving in the auxiliary direction at a predetermined scanning speed is exposed to form an image by controlling dynamically to light arrayed illuminants according to image data, a detector for a position of a print head17detects a deviation from a predetermined standard fixing point generating a deviating position detecting signal. A memory control circuit14selects as an exposing data from image data of the k−1 (k is an integer greater than 1) precedent line to image data of the current line based on a correcting value determined in accordance with a deviation denoted by the position-detecting signal. The arrayed illuminants are dynamically controlled to light whereby an exposing head position detecting device can detect a deviation from the standard fixing position according to the distribution of the received light from light emitting elements provided to each of the exposing head.
