摘要： An optical scanning device that emits a light beam and scans a scanning subject with the light beam, includes: a holder mounted with a light source that emits the light beam, a collimator lens that converts the emitted light beam to approximately collimated beam, and a slit that interrupts apart of the collimated beam; a deflector having a reflecting surface, the deflector deflecting the light beam emitted from the light source; a cylindrical lens that focuses the light beam that has passed through the slit onto the reflecting surface of the deflector; and a frame having a base stage that is mounted with the deflector and the cylindrical lens. The holder is fixed to the frame by bonding with an adhesive in such a manner that a bottom end portion of the holder is spaced from a top surface of the base stage.

摘要： In an image forming apparatus, a rigid-body plate, which is to be placed across a scanning unit for constituting a housing, also serves as an upper cover of the scanning unit, and the scanning unit is suspended on the rigid-body plate at an interior position from a top cover of an upper portion of the housing of the image forming apparatus. This obviates a necessity for interposing, between the scanning unit and a photosensitive drum, a rigid-body plate or the like used for mounting the scanning unit, thereby shortening a distance between the scanning unit and the photosensitive drum.

摘要： In an image forming apparatus, a polygon mirror, a plurality of laser generators, a first sensor, and a second sensor are disposed at a frame formed with a resin. A laser beam outputted from the laser generator and deflected by a deflection surface is irradiated onto a photosensitive surface of a photosensitive drum to scan the photosensitive surface over a scan part. The first sensor is disposed at a first position to detect a laser beam deflected by the deflection surface. The second sensor is disposed at a second position to detect a laser beam deflected by the deflection surface. A storage unit stores correspondence information indicating shift of the scan part from a reference scan part in relation to time difference between detections of the laser beam by the first sensor and the laser beam by the second sensor. The correspondence information varies with temperature variation in the frame. A controller controls the laser generator to output a laser beam based on the shift of the scan part.

摘要： In a laser beam scanner according to the invention, L2/L1>L4/L3 is satisfied, where L2/L1 is the lateral magnification in the sub-scanning direction in an optical path from a polygon mirror to a photosensitive drum, and L4/L3 is the lateral magnification in the sub-scanning direction in an optical path from the polygon mirror to a beam detector. Accordingly, the light-receiving width of the beam detector can be reduced as compared with a conventional laser beam scanner where L2/L1=L4/L3.
