摘要： A charging device (10) in an image forming apparatus is provided with an image carrier such as a photosensitive drum (12) or image forming medium on which an electrostatic latent image is developed. The charging device has a brush roller (14) for charging the carrier. The roller brush is rotatably mounted and formed with inclined fibers planted on a shaft, the roller brush satisfying the following formulas: L₂ ≦ L₁-0.5 L₂ ≧ L₁×0.5
wherein L represents a length of fibers and L represents a thickness of the brush. The charging device further has means (28) for removing the charges from the surface of the brush roller and means (28) for cleaning an area where the charges are removed by the charge removing means.摘要翻译： 图像形成装置中的充电装置设置有诸如感光鼓或图像形成介质的图像载体，静电放电图像显影在其上。 充电装置具有用于对载体充电的刷辊。 辊刷可旋转地安装并形成有植入在轴上的倾斜纤维，该辊刷满足以下公式：其中L表示纤维的长度，L表示刷的厚度。 充电装置还具有用于从刷辊的表面去除电荷的装置和用于清除通过电荷去除装置去除电荷的区域的装置。
