Abstract
A developing apparatus equipped with a sleeve and a scraper member to scrape off the developer from the circumferential surface of the sleeve, wherein the scraper member is normally urged resiliently in the direction which considerably separates it from the circumferential surface of the sleeve, and when there is developer on the scraper member the tip of the scraper member comes close to the circumferential surface of the sleeve. A gap is defined in a limited width between the sleeve and a restriction member for restricting the flow rate of the developer. The gap can be non-uniformly changed along the axial direction of the sleeve.
