PURPOSE:To prevent stains of an optical exposure system and to enhance imaging performance, by providing solid light-emitting elements and an image-forming optical system, and a developing device facing each other across a photoreceptor. CONSTITUTION:An object 8 is projected and imaged on a point 8' by reflecting a light cast from the object 8 with the first reflective face 9 of a reflecting member 10 having 2 reflective faces 9, 9', passing it through a lens 11, reflecting it with 2 reflective mirrors 13, 13 of a dach mirror 12, that is, a roof-type reflective member to change the light path, reflecting it with the second reflective face 9'. An image recording apparatus using this optical system, e.g. has such a structure that an emitted light pattern of solid light emitting diodes is projected on a drum-like photoreceptor 3 by 2 optical systems arranged in the inside of the photoreceptor 3. |
