An optical printer head that can, at a low cost, prevent the dimming of light at a lens, and an image forming apparatus that uses such an optical printer head are provided. A lens controls light, emitted by LEDs, that is used to irradiate a photosensitive drum. And since the lens is coated with a layer of resin, the resin prevents the occurrence of a chemical reaction between nitric acid, generated as a consequence of the production of ozone, and an alkali component on the surface of the lens, and prevents the dimming of light at the lens.
