Zusammenfassung:	An image forming device, characterized in that the shape of the optical path of a third laser beam from a third semiconductor laser (19M) to a third photo-sensitive member drum (1M) is approximately the same as that of the optical path of a first laser beam from a first semiconductor laser (19C) to a first photo-sensitive member drum (1C), a second virtual line connecting the rotating center of the third photo-sensitive member drum (1M) to the rotating center of a fourth photo-sensitive member drum (1K) is tilted relative to a first virtual line connecting the rotating center of the first photo-sensitive member drum (1C) to the rotating center of the second photo-sensitive member drum (1Y), and an angle formed by the rotating axis (x2) of a second rotating polygon mirror (20b) and the second virtual line (12) is equal to an angle formed by the rotating axis (x1) of a first rotating polygon mirror (20a) and the first virtual line (11).
