<p><P>PROBLEM TO BE SOLVED: To provide an optical scanner in which the time until the beginning of correction of a shift is shortened and to provide an image forming apparatus. <P>SOLUTION: The color shift is corrected at a deflection speed slower than the deflection speed of a polygon mirror being a deflection means when a latent image is written on the surface of a photoreceptor being a latent image carrier. Thus, the color shift is corrected at an earlier time than the case where the color shift is corrected after the deflection speed is attained for writing the latent image on the surface of the photoreceptor. Further, the color shift is corrected with low energy and low noise. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
