PROBLEM TO BE SOLVED: To enable only a photoreceptor drum incorporated in a process cartridge to be safely and easily exchanged without generating peripheral stains or the like and to attain reduction of exchanging parts, improvement of economical efficiency due to reduction of running cost and environmental preservation due to reduction of industrial waste by enabling only the photoreceptor drum easily exchanged at a user side. SOLUTION: A drum recovering chamber 53 is set so as to cover the photoreceptor drum 18 of the process cartridge 30 pulled out of a device main body 8 and the used photoreceptor drum 18 is directly recovered in the drum recovering chamber 53 by using a photoreceptor drum case 52 accommodating a new photoreceptor drum 18s at the time of unusing. Then a drum housing chamber 54 is set so as to cover the process cartridge 30 and the new photoreceptor drum 18s is directly mounted on the process cartridge 30 to exchange the photoreceptor drum 18. |
