Abstract
An image forming apparatus includes an image bearing member; a brush roller, rotatable in a predetermined rotational direction, contacted to the 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 appears to be moving when the brush roller rotates in the predetermined rotational direction.
