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.
