Abstract
An image forming apparatus comprises an adjusting mechanism that adjusts an interval between an LED head writing an optical image on a photoreceptor and a photoreceptor drum to a reference interval (A), and the adjusting mechanism includes a regulating member attached to the LED head. In the adjustment of the interval between the LED head and the photoreceptor drum, the LED head and the regulating member are integrally moved until the regulating member comes into contact with the photoreceptor drum. The interval between the LED head and the photoreceptor drum is (A-B) at this point. The LED head and the regulating member are moved in the direction opposite to the photoreceptor drum by a distance (B). As a result, the interval between the LED head and the photoreceptor drum is set to the reference interval (A).
