Abstract:
A developing unit includes a developer bearing member, a container, an end seal, a sheet, and a backup member. The container contains a developer. The container has an opening for supplying the developer to the developer bearing member. The end seal is disposed between the developer bearing member and the developer container. The end seal is disposed at an area of the container outside a longitudinal end of the opening. The sheet seals a gap between the developer bearing member and the container. One widthwise end of the sheet is fixed to the container. The other widthwise end is in contact with the developer bearing member. A longitudinal end of the sheet includes a sandwiched portion between the end seal and the developer bearing member. The backup member is provided in an area facing a surface of the sheet opposite to a surface in contact with the developer bearing member.

Claim (Index 1):
A developing unit comprising:\n a developer bearing member configured to bear a developer; a container containing the developer and rotatably supporting the developer bearing member, the container having an opening for supplying the developer to the developer bearing member, the opening being long in a longitudinal direction of the developer bearing member; an end seal between the developer bearing member and the developer container, the end seal being disposed at an area of the container outside an end of the opening in the longitudinal direction; a sheet that is long in the longitudinal direction, the sheet sealing a gap between the developer bearing member and the container, wherein a first widthwise end of the sheet, in a widthwise direction perpendicular to the longitudinal direction, is fixed to the container, wherein a second widthwise end of the sheet, opposite to the first widthwise end of the sheet in the widthwise direction, is in contact with the developer bearing member, and wherein a longitudinal end of the sheet includes a sandwiched portion sandwiched between the end seal and the developer bearing member; and a backup member provided in an area facing a surface of the sheet opposite to a surface in contact with the developer bearing member, wherein the area is next to the end seal on the opening side in the longitudinal direction and has at least part of the backup member fixed to the container, and wherein the backup member is in contact with the opposite surface of the sheet in a state in which the developer bearing member is supported by the container.
