Abstract
A unit for use with an image forming apparatus. The unit includes a developer accommodating portion, constituted by a frame, for accommodating a developer. A sheet member, provided on the frame in contact with a rotatable member, prevents the developer from leaking out from a gap between the developer accommodating portion and the rotatable member. A resin member fixes the sheet member on the frame. The resin member is formed on the frame by injection molding of a resin material and is fixed to the sheet member by welding. The resin material has an elastic modulus that is less than that of the frame.
