An image forming device equipped with a light scanning device having a polygon mirror that deflects laser light by rotating, a focusing element for focusing deflected laser light onto a photosensitive body, and a reflection mirror reflecting and guiding to the photosensitive body the laser light which passes through the focusing element, given that a distance L between an end surface of the focusing element and the reflection mirror is 8 mm<=L<=25 mm, and an angle Theta formed by incident light and reflected light of the reflection mirror is 25°<=Theta<=45°, the focusing element, the reflection mirror, and the photosensitive body are disposed such that a relationship between L and Theta satisfies 8 mm<=L tan theta<=12 mm is provided.
