Abstract
A regulating device and method regulating the thickness of a toner of an image forming apparatus. The device and method include a blade body for elastically contacting a developing roller supplying toner to a photosensitive medium, and a bending portion bent at a predetermined angle from the contacting portion of the blade body and the developing roller to regulate the layer thickness of the toner that is transferred to the developing roller, wherein the blade portion is formed such that its height is gradually reduced toward both ends of the bending portion so that the toner supplied to the developing roller goes over the ends of the bending portion, and a developing unit employing the same.
