    • The rotating speed of the coating brush of the image forming apparatus fluctuates between the upper limit speed and the lower limit speed across the standard speed. Consequently, the positional relation of the contact between the brush textile of the coating brush and the surface of the photographic sensitive drum varies for a wider range compared to a case where the rotating speed of the coating brush does not vary. Since the thin area of the brush textile moves for a wider range of the surface of the photographic sensitive drum in the axial direction of the rotating shaft of the photographic sensitive drum, the area where the coating amount of the lubricant is less is evened out by the area where the coating amount of the lubricant is rich, thus improving the unevenness of coating of the lubricant on the photographic sensitive drum.
    • 图像形成装置的涂布刷的旋转速度在标准速度之间在上限速度和下限速度之间波动。 因此,与涂膜刷的旋转速度不变的情况相比,涂布刷的刷子织物与感光鼓的表面之间的接触的位置关系变化较大。 由于刷子织物的薄区域在感光鼓的旋转轴的轴向方向上移动感光鼓的表面的较宽范围,所以润滑剂的涂布量较小的区域被 润滑剂的涂布量丰富的区域,从而改善感光鼓上润滑剂的涂布不均匀性。
