<p><P>PROBLEM TO BE SOLVED: To provide an optical writing head of which the large part is in a state where temperature becomes higher than normal temperature when an image is formed and to provide an image forming apparatus. <P>SOLUTION: The large part of the optical writing head arranged in the image forming apparatus is in a state where the temperature becomes higher than the normal temperature when the image is formed. Thus, in the optical writing head, the arrangement interval of a light emitting element array chip is accurate at the temperature higher than the normal temperature and the absolute value of a magnification error is small. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
