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.

The carbonaceous material contains an intercalation substance intercalated between graphenes of a graphene stack and is expanded graphite which shows in an XRD pattern respective peaks in 7-12° and 18-24° ranges of 2θ and in which a peak in 25-27° range has a smaller height than that in 18-24° range and a half width of the peak in 7-12° range is 4 degrees or less. The process for producing the carbonaceous material includes immersing at least a portion of sheet-like graphite or sheet-like pre-expanded graphite into an aqueous electrolyte solution to subject the graphite to an electrochemical treatment. The process for producing exfoliated graphite includes the step of applying an exfoliation force to the carbonaceous material to obtain exfoliated graphite. The exfoliated graphite is obtained by this production process.

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.
