Abstract:
A developing apparatus for developing images held on an image holder, comprising:a developer holder for feeding a developer to a developing position facing the image holder;a layer thickness control member for slidably contacting a face of the developer holder and forming a developer layer having a predetermined thickness on the developer holder; andelastic seals for contacting both the layer thickness control member and the developer holder and restricting a movement of the developer on the developer holder in a longitudinal direction orthogonal to a feeding direction of the developer;wherein a width of the layer thickness control member in the longitudinal direction is wider than a width of the developer holder in the longitudinal direction and the seals have side edges where at least one side edge of each seal is inside the corresponding edge of the developer holder to form inner side edges: and wherein the inner side edges of the seals are aligned to side edges of a predetermined image area on the image holder.
