<P>PROBLEM TO BE SOLVED: To prevent a color shift due to frequency modulation when images are formed by modulating the frequency of an image clock using a predetermined fluctuation amount. <P>SOLUTION: When frequency modulation of the image clock is performed, light emission signal generation unit 101 controls frequency change profiles of the modulation image clock so that the profiles become the same ones relative to image positions drawn by each laser. <P>COPYRIGHT: (C)2012,JPO&INPIT |
