摘要： Provided is a sealing member for preventing leakage of a developer from a developer containing portion of a process cartridge detachable from a main body of an electrophotographic image forming apparatus to an outside of the developer containing portion. The sealing member is made of a thermoplastic elastomer that contains at least a copolymer and a plasticizer. In a molecular weight distribution of a tetrahydrofuran soluble matter of the thermoplastic elastomer measured by gel permeation chromatography, at least one peak is present in each of a region of a molecular weight of 4,000 or less and a region of a molecular weight of 30,000 to 200,000, and a percentage of a component of a molecular weight of 800 or less in a region of a molecular weight of 5,000 or less is 30% or less.

摘要： A developing device frame unit supporting a regulating member regulating the layer thickness of developer on a developer carrier. The unit includes a frame having a seal forming portion, first and second, first and second end seals contactable to the carrier surface to prevent carrier-axial-direction leaking of the developer, and a blade sealer sealing between the regulating member and the frame to prevent developer leaking when the regulating member is mounted. The blade sealer is an elastomer resin material which is injection-molded with a metal mold and in the seal forming portion where the end seals are provided. The blade sealer connects the end seals with each other, and a protrusion provided by a squeezed-out portion of the resin material is provided by injecting, into a space defined by the metal mold, the seal forming portion, and the end seal seals, a resin material volume larger than a volume of the space.
