Claims

[Claims for Utility Model Registration] A light source section, a rotary deflection means for scanning a laser beam emitted from the light source section, and a laser beam scanned by the rotary deflection means on a photoreceptor disposed within the main body. In an image forming apparatus having an optical box housing a lens system for forming an image, the optical box is fixed to a main body frame, and a position adjustment means for engaging the optical box is attached to the main body frame. An image forming apparatus in which the relative positional relationship between the optical box and the photoreceptor can be adjusted by slightly moving the position adjustment means that are engaged with each other.
