Abstract
A cleaning unit usable with an image forming apparatus includes a cleaning blade, supported by a frame and including a free end contactable to an image bearing drum, for removing a developer from the drum; a first seal provided between the frame and the blade by injection molding into the frame adjacent to a longitudinal end portion of the blade, the first seal being effective to prevent developer leakage; and a second seal provided between the drum and the frame in contact with the free end of the blade adjacent to the longitudinal end portion, wherein the first seal includes a seal portion contacting the blade, and a seat supporting the second seal, the seat being deformable to move the second seal to urge the second seal to the free end of the blade when the drum is mounted to the frame.
