摘要： An image forming apparatus includes an image bearing member; a developer carrying member, contactable to the image bearing member, for carrying a developer to a developing position to develop an electrostatic image formed on the image bearing member with the developer; a supplying member for supplying the developer to the developer carrying member, wherein a peripheral speed of the developer carrying member is not less than 1.05 times and not more than 1.20 times a peripheral speed of the image bearing member, and an arithmetic average roughness Ra is not less than 0.20 times and not more than 0.33 times a volume average particle size of the developer, wherein a potential applied to the supplying member is different from a potential applied to the developer carrying member toward a larger potential of a regular charge polarity of the developer.

摘要： 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.
