    摘要: Power transmission members which transmit rotational drive force from a drive source such as a motor, to an intermediate transfer drum is elastically deformed due to a load change which is generated as a cleaning part contacts and moves away from the intermediate transfer drum. Registration control amounts (Ra, Rb and Rc) attributed to the elastic deformation are obtained in advance. Transfer start positions for toner images in at least one or more toner colors out of four toner colors are corrected based on the registration control amounts (Ra, Rb and Rc), whereby registration deviations are suppressed to minimum and a high-quality color image is obtained.

    摘要: An improved optical scanning apparatus is adapted to be such that at either end of the scan range, an optical beam deflected by a reflecting surface of a scanner will pass through an anamorphic lens in scanning optics at a position spaced from its optical axis in the sub-scanning direction. The anamorphic lens has such a sectional profile in the sub-scanning direction that the lens thickness at one end of the sub-scanning direction differs from the thickness at the other end. Also, a high speed optical scanning apparatus based on the dual incidence and the oblique incidence, can prevent a positional variation of a scanning line that is due to a shift of each facet of the rotating polygonal mirror, which is caused by an offset of the rotating axis of the rotating polygonal mirror. The scanning apparatus includes a light source, a rotating polygonal mirror with a plural number of reflecting surfaces for reflecting and deflecting an optical beam emitted from the light source, transfer optics for receiving the optical beam that is reflected and deflected by a first reflecting surface of the rotating polygonal mirror and transferring the optical beam to a second reflecting surface of the mirror, and scanning optics for scanning a scanned surface with the optical beam that is reflected and deflected by the second reflecting surface.

    摘要: The improved beam scanning apparatus has an optical element that is driven to rotate by means of a drive means so as to be capable of continuous angular displacement with respect to the beam from a light source. The optical element deflects the incident beam so that it is focused to form image on the image plane. It is provided with an entrance face, a reflecting face and an exit face which have their shape specified in such a way as to achieve effective correction of aberration, provide higher resolution, and reduce the size and cost of the apparatus.

    摘要: An optical scanner that has a simple construction and which yet exhibits satisfactory imaging performance under varying temperature conditions. Of the two orthogonal scanning cross sections of scanning optics (i.e., the main and sub-scanning cross sections), the one that involves the greater movement of the image plane due to the temperature-dependent changes in optical characteristics (e.g. the variation in the operating wavelength of a light source, the index variation of a lens material and the thermal expansion of a lens itself) is adapted to be the same as the other cross section that involves the greater movement of the image plane due to the change in the distance from the light source to a collimator lens. If necessary, additional correction is effected in such a way that the scanning cross section that involves the greater overall movement of the image plane after correction for temperature changes is adapted to be different from the cross section that involves the greater amount of optical field curvature.

    摘要: In a line head, a plurality of light emitters are arrayed on a substrate in a first direction. Each of the light emitters is operable to emit a light beam. In a rod lens array, a plurality of rod lenses are arrayed in the first direction, and each of the rod lenses is adapted to focus the light beam emitted from an associated one of the light emitters onto a target surface. The substrate and the rod lens array are attached to a holder elongated in the first direction. Positioning members are provided at both end portions of the holder in the first direction. A relative position between the substrate and at least one of the positioning members is variable in a second direction perpendicular to the first direction.
