An image forming apparatus includes an image bearing member; a brush roller, rotatable in a predetermined rotational direction, contacted to said image bearing member; and an applying device for applying a bias to the brush roller. The brush roller includes a shaft and a woven fabric brush including fibers planted in a strip-like base material which is wound helically about the shaft with a helical winding gap. The woven fabric brush is subjected to fiber-slanting processing so that the fibers of the helically wound woven fabric brush are slanted, so as to cover the helical winding gap, from a downstream side toward an upstream side with respect to a longitudinal direction in which a helically extending widthwise edge of the base material is seen moving when the brush roller rotates in the predetermined rotational direction. |
