Abstract: Disclosed is a one-component developing apparatus in which a developing agent scale-off member such as a wire member is provided parallel to the surface of the developing agent carrier so as to be in contact with or in close proximity to a developing agent carrier. A developing agent thin layer formed on the surface of the developing agent carrier which did not contribute to development in a development region comes into contact with the developing agent scale-off member so as to be forcibly scaled off of the developing agent carrier, so that the image history is erased. When the developing agent scale-off member is made to vibrate, or a bias voltage is applied between the developing agent scale-off member and the developing agent carrier, the developing agent may be scaled off more efficiently.
