PURPOSE:To prevent the re-exposure of a photosensitive body by flare light by providing the photosensitive body facing surface of a member in the vicinity of the photosensitive body near a scanning part by laser beam with a light absorption means and absorbing reflected laser beam by the photosensitive body. CONSTITUTION:The light absorption means 50 is provided on the photosensitive body facing surface of a thermistor PCB46 close to the light scanning part by the laser beam L and to the photosensitive body 10 so as to absorb the reflected laser light RL by the photosensitive body 10. Raw material like matt black coating, a black sheet, black tape, etc., that can effectively prevent the reflection of light is applied to or attached to the photosensitive body facing surface of the member near the photosensitive body 10 so as to form the light absorption means 50. It can absorb the reflected laser light RL and prevent the occurrence of re-reflected light which causes the re-exposure of the photosensitive body. |
