    • An image forming apparatus for forming a latent image by image exposure on an image bearing member which is charged by a charge brush of a charging device, and developing the latent image by a developing device, transferring the developed image on a sheet, and cleaning the residual toner on the image bearing member by the developing device. The rotational brush rotates in such a direction that a contacting portion of the brush with the image bearing member moves in the same direction as a moving direction of a surface of the image bearing member, and is provided to satisfy the following condition:20.ltoreq.(N).sup.2 /t.ltoreq.35,wherein N is a contact nip width between the charging brush and the image bearing member and t is a thickness of the charging brush.
    • 一种图像形成装置,用于通过图像曝光在由充电装置的电荷刷充电的图像承载部件上形成潜像,并通过显影装置显影潜像,将显影图像转印在片材上,并且清洁 通过显影装置在图像承载部件上残留调色剂。 旋转刷沿着刷子与图像承载部件的接触部分沿与图像承载部件的表面的移动方向相同的方向移动的方向旋转,并且被设置为满足以下条件: =(N)2 / t <35,其中N是充电刷和图像承载部件之间的接触夹持宽度,t是充电刷的厚度。
