PURPOSE:To facilitate the cleaning of a screen lamp by providing a cleaning tool touching the surface opposed to the rear surface of a belt-like photoreceptor in a sliding piece which is provided slidably in the length direction. CONSTITUTION:A sliding piece 51 is provided slidably in the length direction along a rail part formed in the upper part of a lamp housing 30, and is provided with a cleaning tool, such as a brush, so as to touch the upper surface of a dust protective shield 32, and a long-size handle 53 provided on the sliding piece 51 projects outwardly from the notched part 54 of a front longitudinal plate 10. Accordingly, when a movable piece 51 is drawn out and pushed by the handle 53 from in the notched part 54 of the front longitudinal plate 10, the cleaning tool 52 is slid along the dust protective shield 32. Therefore, a foreign material such as floating toner stuck to the upper surface of the screen lamp 28 can be cleaned up without the detachment of the belt-like photoreceptor. |
