Image forming apparatus and adjusting method of image forming apparatus
First Claim
1. An image forming apparatus comprising an adjusting mechanism that adjusts an interval between a write head writing an optical image on a photoreceptor and the photoreceptor to a reference interval, the adjusting mechanism including a regulating member that integrally moves along with the write head in the direction of the photoreceptor to regulate the interval between the write head and the photoreceptor;
- a moving mechanism that integrally moves the regulating member along with the write head to bring the regulating member into contact with the photoreceptor; and
a reverse-moving mechanism that integrally moves the regulating member along with the write head in the direction opposite to the photoreceptor by a predetermined distance after the regulating member comes into contact with the photoreceptor to set the interval between the write head and the photoreceptor to the reference interval.

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).
