A charge erasing means support device for an image forming apparatus in which the erasing means is rotatably installed about an axis parallel to the rotational axis of the image carrier, comprising: a cover disposed in the attachment/detachment direction of the image carrier; urging means for urging the charge erasing means in a direction away from the image carrier; and a biasing means for resisting the biasing force of the charge erasing means at a position where the charge erasing means is close to the image carrier. A charge erasing means support device for an image forming apparatus, further comprising a fixing means for fixing the charge erasing means to the cover.
