摘要： A toner cartridge for an image forming apparatus which can detect the remaining state of a developer even when the developer in the cartridge is biased by the rotation and stirring of a rotary conveyance body. A developer detector arranged outside the toner cartridge has a light projecting unit and a light receiving unit, and the toner cartridge has detection windows through which light projected from the light projecting unit is input and output. The optical axis of an optical path from the light projecting unit to the light receiving unit intersects the rotary shaft of the rotary conveyance body in the toner cartridge or becomes parallel to the moving direction of the developer. The remaining state of the developer is detected according to whether the optical path going from the light projecting unit to the light receiving unit is cut off or not.

摘要： Provided is a production method which can attain exfoliating treatment of graphite and a process of grafting a polymer onto exfoliated graphite simultaneously and thus makes it possible to easily obtain an exfoliated graphite-polymer composite material in a short time. A method for producing an exfoliated graphite-polymer composite material includes a step of mixing graphite or primary exfoliated graphite, a depolymerizable monomer of which the polymer is decomposed by heating to generate radicals and also to form a monomer or an oligomer, or the polymer A of the monomer, or a polymer B which forms radicals at a temperature close to its decomposition temperature to obtain a mixture; and a heating step of putting the mixture in a non-open container to heat the mixture to a first temperature range from the ceiling temperature or higher to the onset decomposition temperature or lower, or to a temperature higher than the first temperature range.

摘要： A lens holder 2 holds an objective lens 1. Wires 5a.about.5d movably support the lens holder 2 relative to a stationary member 6 in a tracking direction and in a focus direction. The wires 5a.about.5d are integrally formed with the lens holder 2 and the stationary member 6 and one end and the other end of each of the wires are buried in the lens holder 2 and the stationary member 6. At a time of the integral molding, parts of the buried portions of the wires 5a.about.5d are exposed in notches 2a.about.2d and 6a.about.6d to be in contact with a mold for molding, thereby injection pressure of a molding material is received by the mold. This makes it possible to prevent deformation of the wires 5a.about.5d due to the injection pressure of the molding material, resulting in reducing inclination during actuation and degradation of frequency response characteristic.
