发明名称 Developing apparatus for preventing developer from leaking from a developer container
摘要 A developing apparatus includes a developer container, having an opening, for containing a developer, a developer carrying member in the opening, an elastic developer layer thickness regulating member, elastically press-contacted to the developer carrying member and extended along a length of the developer carrying member, for regulating a thickness of a layer of the developer on the developer carrying member, a pair of end seals, contacted to longitudinal end portions of the developer carrying member, for preventing movement of the developer to an end of the developer container wherein a surface of the pair of end seals adjacent to the regulating member are press-contacted to longitudinal end surfaces of the regulating member, and a developer scatter preventing sheet cooperating with the developer carrying member to form a nip permitting passage of the developer into the container while preventing scattering of the developer. The distance between the sealing members at the nip is larger than the distance therebetween at the regulating portion.
