Abstract:
1. A developer container comprising: a rotatable member mounted to a frame and rotatably carrying a developer on its peripheral surface; an end sealing member, mounted to the frame and disposed between the frame and a peripheral surface of said rotatable member at a longitudinal end portion of said rotatable member, that suppresses leakage of the developer between the frame and said rotatable member; a sheet that suppresses leakage of the developer between the frame and said rotatable member, said sheet being mounted to the frame and extended over the length of said rotatable member between the frame and a peripheral surface of said rotatable member, and wherein said sheet enters between said end sealing member and the peripheral surface of said rotatable member at the longitudinal end portion of said rotatable member, wherein the frame is provided with a through hole penetrating the frame at the longitudinal end portion of said rotatable member, wherein one end opening of the through hole is opposed to said rotatable member with said sheet therebetween, and the other end opening of the through hole is not opposed to said rotatable member; a thermoplastic elastomer that suppresses leakage of the developer through a clearance among the frame, said end sealing member and said sheet, said thermoplastic elastomer being injected into the through hole from the other end opening toward the one end opening to fill the clearance among the end sealing member, the sheet and the frame with thermoplastic elastomer.
