A seal assembly may be used to seal an interface between a roller and a frame in an image forming apparatus. The seal assembly may include an end seal configured to seal an end of a doctor blade in contact with the roller and a roll seal configured to seal a portion of an outer surface of the roller. The roll seal may include an extension located between the end seal and the roller. The roll seal may also include a toe portion that engages the developer frame to resist movement of the roll seal when the developer roll rotates against the roll seal. The seal assembly may be used in an image forming apparatus including, but not limited to, printers, copiers, faxes, multifunctional devices or all-in-one devices.
