<p>PURPOSE:To expose at the correct position of a photosensitive body, to execute high-quality recording without positional deviation and to improve a yield for manufacturing an exposure source by previously measuring the positional deviation of a dot from the reference positions of the respective light emitting elements of an LED array, and correcting the exposure of the respective light emitting elements of an exposure part based on the positional deviation. CONSTITUTION:When a recording pattern being an object to be exposed is outputted by a recording pattern output part 300, the information of the positional deviation showing the deviation from the reference positions of the respective light emitting elements of the exposure part 100 is generated by a positional deviation information generation part 400 at the same time. The information of the positional deviation is generated by previously measuring the deviation of the respective light emitting elements of the exposure part 100 from the reference position and regarding the deviation of the concerned position as the information of the positional deviation. The information of the positional deviation and the recording pattern are sent to a correction exposure control means 200 and the exposure of the respective light emitting elements of the exposure part 100 is decided by the control means 200 based on the information of the positional deviation and the recording pattern. Then, the control of light emission corresponding to the concerned exposure is executed.</p> |
