置。[Claim for Utility Model Registration] The toner is placed on a photoreceptor drum or the like at a predetermined interval, and is exposed to the toner transfer area with a thin layer of toner of a predetermined thickness formed on the surface of the photoreceptor drum. In a developing device equipped with a developing roller that causes toner to fly onto an electrostatic latent image formed on the surface of a surface of a toner image, the developing roller is pressed into contact with the developing roller on the downstream side of the toner transfer portion of the developing roller, A copying machine comprising: a seal roller made of an elastic body that rotates at substantially the same speed as the rotation of the roller; and a seal blade that contacts a downstream side of the pressing portion of the seal roller. Toner seal device for developer.
