An apparatus is provided capable of guiding regular reflected light from a reading surface to a reflecting mirror when light is irradiated from two directions from light sources to the reading surface, and is suitable to read a gloss image. The light sources for irradiating light to the reading surface from the two directions of different angles are configured of a first light emitter and a second light emitter, a mirror reflecting surface for specularly reflecting light and a translucent surface for passing light therethrough being formed on the surface of a reflecting member for deflecting light from the reading surface to a predetermined reading light path direction, the first light emitter being arranged between the platen and the platen side surface of the reflecting member, the second light emitter being arranged at the back surface of the reflecting member so as to irradiate light on the reading surface through the translucent surface.
