摘要:
A first component part formed of a first styrene resin composition and a second component part formed of a second styrene resin composition are fastened by solvent welding by means of a terpene type solvent, to provide a cartridge which is almost free of deformation at the peripheries of joints, has a high positioning precision for component parts and has a high rigidity.

A cartridge mounted on an electrophotographic image forming apparatus includes a molded resin complex in which a first resin molded product and a second resin molded product are engaged with each other so as to be separable. The first resin molded product is obtained by molding a first resin pervious to laser light, and the second resin molded product is obtained by molding a second resin absorptive to laser light. The first resin molded product and the second resin molded product are engaged with each other so as to be separable, by one or more protrusions of the second resin molded product which is formed by applying laser light from the first resin molded product side while placing the first resin molded product and the second resin molded product either in a close state or in a contact state. The cartridge further includes a developer containing frame containing a developer and a handle for drawing out a sealing member sealing a developer supplying opening of the developer containing frame, in which the first resin molded product is the handle, and the second resin molded product is the developer containing frame.

A method of remanufacturing a cartridge detachably mountable in an electrophotographic image-forming apparatus body and composed of styrene-based resin compositions at least in part, characterized by including the steps of: (1) dividing the cartridge into at least two parts; and (2) bonding at least one of the divided parts with another one of the divided parts and/or a component other than the divided parts by use of a terpene solvent.

A molded resin complex is provided including a first resin molded product and a second resin molded product engaged with each other so as to be separable. The first resin molded product is obtained by molding a first resin having transparency with respect to laser light, the second resin molded product is obtained by molding a second resin pervious to laser light, and the first resin molded product and the second resin molded product are engaged with each other so as to be separable by one or more protrusions of the second resin molded product which are formed by applying laser light from the first resin molded product side while placing the first resin molded product and the second resin molded product either in a close state or in a contact state.
摘要:
To provide a cartridge and a toner container each of which does not increase a material cost and is excellent in impact resistance against, for example, a vibration or a fall, the impact resistance being a needed function. The cartridge and the toner container each include a first part molded out of a laser light absorptive styrene resin composition and a second part molded out of a laser light transmissive styrene resin composition, the first part and the second part being joined with each other by laser welding. In each of the cartridge and the toner container, the transmittance of each of the parts is adjusted depending on, for example, the particle size and amount of rubber in each of the styrene resin compositions, or the kind of a flame retardant in each of the compositions.

A process cartridge includes a drum; a rotatable roller including a first shaft end portion and a second shaft end portion; a bearing member for rotatably supporting ends of a shaft of the rotatable roller; an urging member for urging the rotatable roller via the bearing member in a drum contact direction; a cartridge frame for rotatably supporting the drum and for movably holding the rotatable roller via the bearing member; a movable guide member movable in an axial direction of the shaft of the rotatable roller and including a first contact portion; and a fixed guide member including a second contact portion. At least one of the first contact portion and the first shaft end portion has an inclined surface inclined with respect to the axial direction of the rotatable roller, and at least one of the second contact portion and the second shaft end portion has an inclined surface inclined with respect to the axial direction of the rotatable roller.
摘要:
A developing device facing an image carrier and including a developer carrier, a developer flying control member, and a development-noise control member. The developing device develops an electrostatic image formed on the image carrier by causing the developer to fly from the developer carrier to the image carrier upon an application of an alternating-current bias to the developer carrier. Noise produced by the development-noise control member vibrated by an oscillating electric field of the alternating-current bias is smaller than a noise produced by the developer flying control member vibrated by the oscillating electric field.
