PURPOSE:To control multiple reflection in the photosensitive body and to always record high quality images by providing a layer, which prevents regular reflection of incident light, between a photosensitive body and a base when an image is recorded by means of exposing optical signals on a photosensitive recording medium. CONSTITUTION:When a light beam of a long wavelength region which has inefficient light absorptance in the photosensitive body 41, for example, a laser beam emitted from a semiconductor laser, is used to expose the photosensitive body 41, the layer 43 made of a substance which has high light absorption coefficient is provided between the photosensitive body 41 and its base 42. Therefore, most of the light which transmits the photosensitive body is absorbed by the light absorbing layer 43, and the light reflection on the surface of base 42 is suppressed. Thus influence caused by the multiple reflection is suppressed, and high quality images are recorded. |
