PROBLEM TO BE SOLVED: To provide a noise prevention mechanism prepared for a high voltage applied body and capable of preventing the occurrence of spark discharge due to defective contact between the rotating shaft of the high voltage applied body and a member attached to the rotating shaft and capable of discharging charge from the high voltage applied body. SOLUTION: The noise prevention mechanism for the high voltage applied body is provided with a photosensitive drum shaft 51KS, a photosensitive drum 51K allowed to be rotated by being carried by the shaft 51KS and allowed to receive the application of high voltage, a brush 100KB2 slidably attached to the shaft 51KS and capable of discharging the charge of the drum 51K to a casing, and a low voltage power supply 100K for applying a bias current to a contact point between the shaft 51KS and the brush 100KB2. |
