To provide an electrifying device that can reduce the load torque of a motor for moving a plurality of cleaning members that individually clean a plurality of grids.SOLUTION: An electrifying device 50 comprises: a carriage 60 that integrally holds a cleaning brush 62 that cleans a grid 56 and a cleaning brush 63 that cleans a grid 57; and a screw member 61 that moves the carriage 60 along the direction of the axis of rotation of a photoconductor drum 1. The slide resistance between the cleaning brush 62 and the grid 56 is configured to be larger than the slide resistance between the cleaning brush 63 and the grid 57. In a direction orthogonal to the direction of the axis of rotation of the photoconductor drum 1, the distance between the cleaning brush 62 and the screw member 61 is shorter than the distance between the cleaning brush 63 and the screw member 61.SELECTED DRAWING: Figure 6 【課題】複数のグリッドをそれぞれ清掃する複数の清掃部材を移動させるためのモータの負荷トルクの低減を図ることができる帯電装置を提供する。【解決手段】帯電装置５０は、グリッド５６を清掃する清掃ブラシ６２とグリッド５７を清掃する清掃ブラシ６３とを一体的に保持するキャリッジ６０と、キャリッジ６０を感光ドラム１の回転軸線方向に沿って移動させるスクリュー部材６１と、を備え、清掃ブラシ６２とのグリッド５６との間の摺動抵抗は、清掃ブラシ６３とのグリッド５７との間の摺動抵抗よりも大きく構成されており、感光ドラム１の回転軸線方向と直交する方向において、清掃ブラシ６２とスクリュー部材６１との間の距離は清掃ブラシ６３とスクリュー部材６１との間の距離よりも短い。【選択図】図６
