PURPOSE:To prevent the deterioration of a photosensitive body due to ozone by adhering sheets including ozonolyzing solution on a face which is confronted with and parallel to the photosensitive body at the upper part of the photosensitive body in the vicinity of to an electrostatic charging device. CONSTITUTION:A photosensitive body unit 20 is constituted of a photosensitive belt 6, driving roller 14, driven roller 15, and grid plate 16, and is integrally attachable and detachable freely for the main body of a device. Then, activated carbon sheets 24 and 25 are respectively adhered on the lower side faces of A and B parts in the vicinity of an electrostatic charger 7, which are confronted with the photosensitive belt 6 of a casing 20a of the photosensitive unit 20, as the ozonolysis solution sheets. That is, the ozonolysis solution sheets, especially, the activated carbon sheets 24 and 25 are adhered on the face extremely near to the photosensitive body. Therefore, residual ozone being the cause of the deterioration of the photosensitive body can be efficiently resolved. Thus, the photosensitive body can be held to have a high quality for a long period. |
