Abstract

PURPOSE:To prevent the toner removed from the outer circumferential surface of a photosensitive drum from being scattered on the circumference by receiving a cleaning tool making sliding contact with the outer circumferential surface of the drum in a cylindrical body, and sucking the cylindrical body inner part by a sucking means. CONSTITUTION:A photosensitive drum 10 to be cleaned is vertically held by a drum support means 20. A cleaning tool 41 in a cylindrical body 44 is rotated by a motor 65, and a suction pump 53 connected to the cylindrical body 44 is driven. The drum support means 20 is lowered, and the drum 10 is inserted to the rotating cleaning tool 41. The fur brush 41a of the cleaning tool makes sliding contact with the whole outer circumferential surface of the photosensitive drum 10 and effectively removes the toner adhered to the outer circumferential surface. As the removed toner is received in the cylindrical body 44 and sucked through a pipe 51 and a filter 52 by the suction pump 53, the toner is never scattered in the cylindrical body 44.

(Problems to be Solved by the Invention) In such image inspection of a photoreceptor drum, toner adhering to the outer peripheral surface of the photoreceptor drum is manually wiped off after the inspection. Well, the work efficiency is bad, and
If toner is firmly attached to the outer peripheral surface of the photoreceptor drum, there is a possibility that such toner cannot be removed. In this case, even if the toner is removed, there is a risk of damaging the surface of the photosensitive drum. Furthermore, it is difficult to uniformly clean the outer peripheral surface of the photoreceptor drum, and uneven wiping is likely to occur. Furthermore, there is also the problem that toner removed from the outer peripheral surface of the photoreceptor drum is scattered around, deteriorating the working environment.
