A cleaning device includes a blade disposed so as to contact an image bearing body that bears a developer image. The blade scrapes off a developer adhering to the image bearing body. The blade has an edge portion including first and second surfaces, and is configured so that a distance between the first and second surfaces decreases toward a tip of the edge portion. The first and second surfaces form a predetermined edge angle at the tip of the edge portion. An area of the first surface is smaller than an area of the second surface, and the first surface contacts the image bearing body.
