PURPOSE:To prevent effectively various trouble originating from a toner scatter by covering a gap part between the front surface and a developing unit photosensitive body with the 1st toner scatter preventing body which is formed detachably and a gap part between a flank and the photosensitive body with the 2nd toner scatter preventing body. CONSTITUTION:There is a large gap between the opening part 114 of a casing 102 and the photosensitive body 16 before a toner scatter preventing body 150 is attached to the casing 102, but this gap is almost sealed after the toner scatter preventing body 150 is attached. Namely, the front end of the flexible member 154 of the toner scatter preventing body 150 adjoins to or contacts slightly the surface of the photosensitive body 16. The 2nd toner scatter preventing body 180, on the other hand, is attached to the casing 102 together with a side wall 126 when the side wall 126 is attached. Namely, the toner scatter preventing body 180 is attached to the side wall 126 in both directions of arrows F1 and F3 in figure and the gap of the flank of the casing 102 is almost covered with the toner scatter preventing body 180. |
