Summary:PURPOSE:To improve the efficiency of cleaning work in a shield case by dropping and housing dust scraped up from the inner surface of the case by allowing a cleaning member to slide in the case into a dust receiver provided outside the case. CONSTITUTION:The cleaning member 7 is provided in an insulating block 5 so that it may come in contact with the inner surface of the shield case 2 in order to remove the dust in the case 2 when a charger 1 is separated from the inside of the case 2 to the outside thereof. A large hole 12 through which the cleaning member 7 is allowed to pass almost in a non-contact state and the dust scraped up is dropped into a box when the charger 1 is separated from the case 2 is provided on the side wall 10a of the dust receiver 10 disposed at an aperture part 2a at one end side of the case 2, and a small hole 13 through which the member 7 is drawn is provided on the side wall 10b. After the dust in the case 2 cleaned by the member 7 is dropped and housed in the dust receiver 10 when the insulating block 5 passes through the large hole 12, the toner adhering to the member 7 is drawn and dropped through the small hole 13.
