Abstract
Abstract An image recording apparatus for recording an image by controlling the scanning and irradiation of a photosensitive material with a number of optical beams having different wavelengths. The image recording apparatus includes light emitting devices disposed close to one another in a common plane for irradiating the number of beams in parallel with a scanning line. The apparatus further includes a rotatable polygon mirror having reflecting faces for reflecting the irradiated optical beams from the light emitting devices for scanning and exposing the photosensitive material. The light emitting devices are arranged to irradiate the reflecting faces of the polygon mirror at a substantially common point.
