Abstract:
A developing apparatus has a developer carrying member carrying a developer thereon, a developer supplying member for supplying the developer to the developer carrying member, and a scraping member for contacting the developer carrying member upstream of the closest position between the developer carrying member and the developer supplying member with respect to the movement direction of the developer carrying member to thereby scrape off the developer from the developer carrying member. There is formed a developer supplying portion surrounded by the scraping member, the developer carrying member and the developer supplying member for supplying the developer from the developer supplying member to the developer carrying member, and the developer scraped off by the scraping member is conveyed to a collecting passage differing from the closest position.
