PURPOSE:To miniaturize a device and to obtain a sufficient image density and excellent image quality by disposing an exposing head provided with destaticizing and exposing light sources inside a photosensitive body and providing a light shielding plate between the destaticizing and exposing light sources. CONSTITUTION:The exposing head provided with the destaticizing and exposing light sources 9 and 22 inside the drum-like photosensitive body 2. The exposing head 5 and a developing unit 6 are nearly symmetrically arranged via the photosensitive body 2. The light shielding plate 21 is provided between the destaticizing and exposing light sources 8 and 22. The light shielding plate 21 has nonpermeability, and light reflecting properties on its surface on the side of the destaticizing light source 8, so that the plate 21 spreads luminous flux while diffusing the light, for reflecting. On the other hand, the surface on the side of the exposing light source 22, has black matting processing, to absorb the light. Thus, the light shielding plate 21 is provided, so that an exposure is not executed with the light from the destaticizing light source 8. Moreover, the light from the destaticizing light source 8 is reflected by the light shielding plate 21, so that the photosensitive body 2 can be destaticized in a wide area. |
