PURPOSE:To improve the linearity of a scanning line and to improve image quality by preventing distortion so-called BOW from being caused on the scanning line on a photosensitive drum. CONSTITUTION:As to the optical device for an image forming device constituted in a state where a photosensitive body 30 is irradiated with laser beams B1 and B2 through long cylindrical lenses 19 and 29 so as to form an electrostatic latent image, the degree of curve on a flat surface which is nearly perpendicular to an optical path on the long cylindrical lens 19 is constituted to be changed by rotating a warm screw 53 for adjustment. |
