PURPOSE: To remove foreign matter infiltrated inside an image forming body, and to maintain an excellent image without giving a damage on a transparent substrate of the image forming body and decreasing a transmissibility, by providing sticking parts for sticking the foreign matter on an inside periphery of the image forming body. CONSTITUTION: This photoreceptor drum 1 is provided with the sticking parts P1 and P2 on both end parts on the inside periphery for instance, a both-side adhesive tape is stuck or the adhesive member is applied thereon. When the photoreceptor drum 10 is rotated in case of the image forming, the inside foreign matter is put on to both end part and allowed to stick on the sticking parts P1 and P2. Moreover, when a process cartridge is pulled out, by patting a side face thereof while arranging the process cartridge in specific bias, the inside foreign matter is pressed to the either end part, and is stuck on the sticking parts P1 or P2. Moreover, a cleaning roller 210, is brought into press contact with the photoreceptor drum 10 and driven-rotated by the photoreceptor drum 10, to scrape off the foreign matter stuck on an inner periphery of the transparent substrate on the inside of the photoreceptor drum 10, and then to send them toward either end part and to stuck on either the sticking part P1 or P2. |
