摘要： PROBLEM TO BE SOLVED: To effectively suppress influence by irregular electrification caused by adhesion of a discharge product even when such irregular electrification occurs. SOLUTION: By noticing a situation that the irregular electrification of a photoreceptor drum 21 by the influence of the discharge product is lessened as a distance between each cat whisker 61a and a grid electrode 63 becomes longer, movement control of a cat whisker holder 61 by a controller 51 is performed, that is, to control such that a rotational angle of a stepping motor 68 is controlled as a discharge cumulative time gets longer, whereby the cat whisker holder 61 is moved in an arrow direction B where it is separated from the grid electrode 63 and the distance between the cat whisker 61a and the grid electrode 63 is extended is performed. Thus, the influence of the discharge product adhering to the cat whisker 61a is suppressed to reduce the irregular electrification of the photoreceptor drum 21. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce uneven charging further effectively by suppressing production and adhesion of a discharge product by gradually changing the direction of ozone flow. SOLUTION: Discharging time of each catwhisker 51 or charging time of a photoreceptor drum 3 is counted, a cylindrical sliding section 54 is rotated in the direction of the arrow D by a rotation driving section 56 whenever the counted time increases by a certain time, and the position of each catwhisker 51 is changed. Thus, even if ozone is generated by discharge of each catwhisker 51, the route of the ozone flow around each catwhisker 51 varies without being fixed, the accident that ozone continues to collect only to a specific catwhisker and the discharge product continues to adhere does not occur, and the charging failure of the photoreceptor drum 3 can be prevented from being caused by the adhesion of the discharge product.

SOLUTION: The charging device 1 includes a needle electrode 2, a support 4, a cleaning roller 5, and a scraping member 60. The needle electrode 2 has the plurality of needles 2A arranged in a straight line along an arranging direction X. The support 4 is disposed so as to freely move along the arranging direction X. The cleaning roller 5 is supported by the support 4 so as to freely rotate. When the support 4 moves, the cleaning roller moves while rotating along the arranging direction X. Consequently, the leading tips of the plurality of needles 2A are exposed from inside one after another after buried inside from the periphery. The scraping member 60 is supported by the support 4 so as to freely rotate. When the support 4 moves, the scraping member 60 moves while rotating along the arranging direction X. Consequently, the small-diameter side end 61 of it comes into firm contact with the sides of the needles 2A one after another.
