发明名称 Unit and image forming apparatus
摘要 A unit for use with an image forming apparatus includes: a frame; a developer accommodating portion; a sheet member, contact to a rotatable member and provided on the frame along a longitudinal direction of the rotatable member; a first end portion seal member for preventing, at a longitudinal end portion, the developer from leaking out from between the frame and the rotatable member; and a second end portion seal member for preventing the developer from leaking out from among the first end portion seal member, the sheet member and the frame. The second end portion seal member is formed by injecting, on the frame, a resin material having an elastic modulus smaller than an elastic modulus of the frame so as to contact with the first end portion seal member and the sheet member.

主权项 1. A unit for use with an image forming apparatus, said unit comprising: a frame; a developer accommodating portion, constituted by said frame, for accommodating developer; a first end portion seal member for preventing, at a longitudinal end portion of a rotatable member, the developer from leaking out from between said frame and said rotatable member; and a second end portion seal member for preventing the developer from leaking out from among said first end portion seal member, said second end portion seal member, and said frame, wherein said second end portion seal member is formed by injecting, on said frame, a resin material having an elastic modulus smaller than an elastic modulus of said frame so as to enter said first end portion seal member to be integrated with said first end portion seal member, wherein said second end portion seal member is projected from said frame and inclined with respect to the longitudinal direction.
