ABSTRACT:
A write start position detecting device has a curved mirror positioned in a plane in which a light beam is scanned to form a latent image on a photosensitive drum. The curved mirror is located at a position where a light beam reflected from it illuminates a photoreceptor element prior to the light source starting the writing operation. The photoreceptor element is located at a position, with respect to the curved mirror, ahead of the scanning direction in which the light beam strikes the photosensitive member to form the latent image thereon.
