部材とを設けたことを特徴とする現像装置。[Scope of Claim for Utility Model Registration] Toner in the developing device is supplied to the developing roller by a toner replenishing member, charged by friction, and conveyed to a development position where it comes into contact with the photoconductor.The toner is then formed on the photoconductor through a charging and image exposure process. In a one-component developing device of an image forming apparatus, which develops an electrostatic latent image and returns the toner remaining on the developing roller after development into the developing device to be used for development again, the toner that remains on the developing roller is returned to the developing device from the developing position. a toner transfer member that contacts the developing roller at a position on the peripheral surface of the developing roller upstream from the toner replenishing position by the toner replenishing member, and transfers residual toner on the developing roller and removes it from the developing roller; A developing device comprising: a toner scraping member for scraping off toner from a member into a developing device.
