    摘要: The present invention aims at providing an optical unit, its manufacturing method, and electrophotographic device that can easily and inexpensively achieve a reliable latent image formation on a photosensitive drum, and can form a high-quality image. To realize the above aims, a lens barrel and a collimating lens are bonded only at a single spot, and the bonding orientation is aligned approximately with a main scanning direction. Thereby displacement of the collimating lens caused by a thermal expansion of the adhesive is restricted to the main scanning direction as adjustable by other components.
