| 1. An image forming apparatus comprising:
an adjusting mechanism, including regulating members which are disposed at each of both ends in the width direction of a photoreceptor
of a write head, that adjusts an interval between the write head writing an optical image on the photoreceptor and the photoreceptor
to a reference interval,
wherein the adjusting mechanism detects contact between each of the regulating members and respective non-image forming areas
provided at both ends of the photoreceptor by sensing electric conduction, and then moves the regulating members together
with the write head apart from the surface of the photoreceptor by a predetermined distance to adjust the writing position
of the write head in relation to the surface of the photoreceptor.
