Abstract
An image forming device, characterized in that the shape of the optical path of a third laser beam from a third semiconductor laser (M) to a third photo-sensitive member drum (IM) is approximately the same as that of the optical path of a first laser beam from a first semiconductor laser (C) to a first photo-sensitive member drum (C), a second virtual line connecting the rotating center of the third photo-sensitive member drum (IM) to the rotating center of a fourth photo-sensitive member drum (IK) is tilted relative to a first virtual line connecting the rotating center of the first photo-sensitive member drum (C) to the rotating center of the second photo-sensitive member drum (IY), and an angle formed by the rotating axis (x) of a second rotating polygon mirror () and the second virtual line () is equal to an angle formed by the rotating axis (x) of a first rotating polygon mirror () and the first virtual line ().
