<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus, which never causes degradation of print quality even when a plurality of vibrations acts thereon. <P>SOLUTION: A pitch value obtained by dividing the value of carrying speed of printing paper P at an exposing position by the value of difference between the frequency of vibration resulting from rotating of a rotary system including a polygon mirror 51 and a polygon motor 55 for rotatively driving the polygon mirror 51 and the frequency of vibration resulting from drive of a motor M3 driven for carrying the printing paper P is set to 0 or≥0.3 mm. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
