Image forming apparatus having improved toner carrier arrangement
 A developing apparatus includes toner powder in the form of fine colored powder, a toner carrier, and a frictional controlling member for contacting under a pressure with the toner carrier under pressure to frictionally charge the toner powder and form a thin toner layer on the toner carrier. The toner carrier on which the thin toner layer is formed is rotated so as to transport the thin toner layer to an opposing location on a toner image carrier on which an electrostatic latent image is formed to convert the electrostatic latent image into a visible image. The developing apparatus includes a toner supply roller disposed in rotating contact with the toner carrier at a side of the toner carrier, the frictional controlling member being provided at a position in contact with the toner carrier downstream of the toner supply roller; and a rotatable toner scraping member is provided in a neighboring relationship below the toner supply roller and the frictional controlling member.
