Abstract: A cleaner assembly includes a cleaner blade having a cleaning edge in contact with a photoconductive drum for removing toner therefrom. An elongated seal extends along a length of the cleaner blade such that an opening for capturing toner removed from the photoconductive drum is formed between the cleaning edge and the elongated seal. The elongated seal includes a tab projecting across a longitudinal end section of the cleaner blade such that the tab is positioned between the cleaning edge and the photoconductive drum preventing contact between the cleaning edge and the photoconductive drum. A fabric seal is positioned in a portion of the opening formed between the cleaning edge and the elongated seal at the longitudinal end section of the cleaner blade. At least a portion of the fabric seal is positioned inboard of the tab of the elongated seal along the length of the cleaner blade.

Abstract: A sealing assembly according to one example embodiment includes a housing and an imaging component positioned on the housing. A seal has opposed first and second edges extending along a longitudinal dimension of the seal. A lateral dimension of the seal is perpendicular to the longitudinal dimension and extends in a direction from the first edge to the second edge. The seal is attached to the housing along the first edge and contacts the imaging component along the second edge. Upon attachment to the housing, the seal is elastically deformed from an unassembled state in which the second edge has a first profile that varies in the lateral dimension along the longitudinal dimension to an assembled state in which the second edge is deformed relative to the first profile to a second profile having less variation in the lateral dimension along the longitudinal dimension than the first profile.

Abstract: A developer unit for an electrophotographic image forming device includes a developer roll rotatably mounted on a housing. The developer roll includes a shaft defining a rotational axis and a roll body cylindrically disposed around the shaft to form an outer circumferential surface of the developer roll. An end seal includes a curved rotary seal portion sandwiched between a pocket portion of the housing and the outer circumferential surface of the developer roll, such that an outer circumferential surface of the curved rotary seal portion contacts the pocket portion of the housing and an inner circumferential surface of the curved rotary seal portion contacts the outer circumferential surface of the developer roll. The pocket portion of the housing includes protrusions that contact the outer circumferential surface of the curved rotary seal portion to restrict movement of the end seal along an operative rotational direction of the developer roll.

Abstract: A developer unit for an electrophotographic image forming device includes a developer roll rotatably mounted on a housing. The developer roll includes a roll body cylindrically disposed around a shaft and forming an outer circumferential surface of the developer roll. An axial end of the roll body includes an undercut forming a hollow region in the axial end of the roll body. An elastomeric end seal has a curved rotary seal portion that is sandwiched between a portion of the housing and the outer circumferential surface of the developer roll at the axial end of the developer roll. An interference between the curved rotary seal portion of the end seal and the outer circumferential surface of the developer roll decreases along an axial dimension of the developer roll in a direction from an axially outboard edge of the end seal toward an axially inboard edge of the end seal.

Abstract: An end seal for an electrophotographic image forming device according to one example embodiment includes an elastomeric body having a blade seal portion for sealing against a rear surface of a doctor blade and a curved rotary seal portion that extends from a bottom end of the blade seal portion for sealing against an outer surface of a rotatable developer roll. The end seal includes a cutout in an inner axial side of the body positioned at a point where the rotary seal portion and the blade seal portion meet.
