A removable lid assembly for covering the access opening of a blade housing segment of a Canon developer cartridge wherein the blade housing segment has a cavity therein which intersects with the access opening and contains a cleaning blade and a series of spaced, but transverse, flat web-like members which are arranged to support the cleaning blade. The lid assembly includes an elongated, generally planar member which has portions thereon that define an elongated recess along one edge portion thereof into which a peripheral edge portion which defines the access opening is inserted. A number of spaced, thickened members are fastened in the cavity of the blade housing. Each or the thickened members is provided with a bore, and has portions thereon which define a slot in which one of the transverse web-like members extends to locate and space the thickened members within the cavity. The planar member is provided with a number of spaced holes through which a number of screws extend to engage the bores of the thickened members, thus removably attaching the planar member to the thickened members. The slots in the thickened members and the transverse web-like members cooperate to align the thickened members below the holes in the planar member such that the bores of the thickened members intersect with the holes in the planar member. A seal along the peripheral edge of the planar member seals against the blade housing when the planar member is attached to the thickened members.
