Abstract
Disclosed herein is a conductive brush charging device for charging the surface of an image forming member. The conductive brush charging device includes a conductive brush located so as to rotate in contact with the image forming member, and a developer removing member formed of a porous material and located so as to be kept in surface contact with the conductive brush over the width thereof. When the conductive brush is rotated, the porous developer removing member rubs against the brush along its bristles to thereby remove a developer deposited to the brush. Since the developer removing member is formed of the porous material, the developer removed is retained in numerous pores of the porous developer removing member, thus achieving a long-term cleaning function.
Claims7
A conductive brush charging device for charging a surface of an image forming member, comprising:
- a conductive brush located so as to rotate in contact with said image forming member;
- a voltage applying means for applying a given voltage to said conductive brush;
- and
- a developer removing member formed of a porous material and located so as to be kept in surface contact with said conductive brush over an entire width thereof.
