摘要:
A developing apparatus includes a developer carrying member for carrying a developer to develop an electrostatic latent image formed on and image bearing member, the developer carrying member having an elastic property; scraping/supplying member, contacted into the developer carrying member, for supplying the developer to the developer carrying member and for scraping the developer off the developer carrying member, the scraping/supplying member having an elastic property, wherein the developer carrying member has a hardness which is higher than that of the scraping/supplying member, and wherein the developer carrying member and the scraping/supplying member satisfy that in a state in which the scraping/supplying member is out of contact with the developer carrying member, a radius of curvature of the scraping/supplying member is larger than a radius of curvature of the developer carrying member at a position of contact between the scraping/supplying member and the developer carrying member.
