    Abstract: An optical deflector of an air bearing type has a fixed shaft; a rotary shaft having a hollow portion fitted onto the fixed shaft; a support device disposed between an end portion of the fixed shaft and an end portion of the hollow portion opposite thereto and supporting the rotary shaft in an axial direction thereof; a radial air bearing formed between an inner circumferential face of the hollow portion and an outer circumferential face of the fixed shaft; a polygon mirror fixed to the rotary shaft; a driving device for rotating the rotary shaft; a device for deflecting light irradiated onto the polygon mirror by rotating the rotary shaft through the driving device; a device for forming a flange for fixing the polygon mirror thereto integrally with the rotary shaft; and a device for setting an upper end portion of the support device on a fixed shaft side thereof to be lower than an upper end face of the polygon mirror. The support device has a first magnet directly attached onto an end face of the fixed shaft, a second magnet opposite to the first magnet and attached to the hollow portion of the rotary shaft, and a third magnet opposite to the second magnet and attached to a casing for covering the polygon mirror. Magnetic poles of the first, second and third magnets are opposite to each other to generate magnetic repulsive force.

    Abstract: There is provided a grinding roller for use in a fixing device including a pair of rotary fixing members that rotate while being pressed against each other to form an area of contact, and heat and press a recording medium carrying an unfixed toner image and fed to the area of contact, to thereby fix the unfixed toner image on the recording medium. The grinding roller is configured to grind a surface of a toner image-side rotary member of the pair of rotary fixing members that comes into contact with the unfixed toner image. The grinding roller includes an abrasive grain layer including abrasive grains, forming a surface layer of the grinding roller, and having a surface with irregularities including projections each formed by an aggregate of some of the abrasive grains and larger in size than each of the abrasive grains and recesses formed between the projections.

    Abstract: A liquid discharge head includes a nozzle plate having a discharge port, and a valve facing the nozzle plate to open and close the discharge port. The valve includes a core having a recess, and an elastic member attached to the core. The recess has: an opening rim on a leading end of the core, the opening rim defining an opening of the recess opening toward the discharge port; a bottom face opposite to the opening rim; and a retaining portion having a width wider than a width of a portion other than the retaining portion of the recess in a width direction. the retaining portion disposed in a rear region between the bottom face and a center of the recess. The elastic member includes a first portion fitted into the recess and a second portion projecting from the opening of the recess toward the discharge port.
