光装置の照明装置。 A tube-shaped light bulb, in which a plurality of light-emitting parts are arranged at intervals along the tube axis direction, is placed inside a roughly gutter-shaped main reflector body, and the light emitted from this tube-shaped light bulb is directed to the main reflector body. The light reflected by the copy original placed on the translucent mounting plate is irradiated by the light, and the reflected light reflected by the copy original is passed through a slit formed at the edge of one side of the main reflecting mirror. In an illumination device of an exposure apparatus, which is guided to an optical system and is configured to form an image on a photoreceptor drum via this optical system, a main reflecting mirror is provided at a side edge of the main reflecting mirror near the slit. 1. An illumination device for an exposure apparatus, characterized in that a bent plane portion or a bent curved surface portion is formed that is bent with respect to the direction in which an edge extends.
