    摘要： An optical device includes a rectangular parallelepiped prism including a reflection-transmission surface for reflecting and transmitting light fluxes, a seating surface provided so that a bottom surface of the prism is fixed by an adhesive, and a groove portion provided in a part of the periphery of the seating surface. When the prism is fixed to the seating surface by the adhesive, the groove portion is configured to be capable of receiving the adhesive protruded from between the bottom surface of the prism and the seating surface when the prism is pressed against a first positioning member for determining a position of the prism so that a first side face of the prism is along a predetermined straight line and against a second positioning member for restricting a second side face orthogonal to the first side face of the prism from moving in the direction of the straight line.

    摘要： An image forming apparatus is provided with a light scanning device that directs laser beams emitted from a plurality of laser light sources onto a plurality of photo conductive members via focusing device which includes optical elements and a deflecting device that deflects the beams in a main scanning direction; an image forming device which forms visible images of different colors from images written onto the photoconductive members by the light scanning device; and an intermediate transfer member or a recording sheet transport member capable of carrying the visible images formed on the photoconductive members. When in detection mode, a control device controls the correction of color registration errors between each color forms patterns on an intermediate belt by means of the image forming device, detects the patterns by a color registration error detection sensor, and stores the color registration error correction values obtained from the detection output of the sensor in a memory device. When forming images, the control device reads the color registration error correction values stored in the memory device, and carries out correction in accordance with the correction values via a writing start position correction device which deflects the laser position in the sub scanning direction. Alternatively, when in detection mode, the control device controls the correction of color registration errors between each color forms color registration error detection patterns on a transfer member belt, sets the scan line from among the plurality of scan lines obtained by a pattern detection sensor for the color that passes through the lens that is most distant from the polygon mirror, as the standard scan line, and stores data for the standard scan line and bending correction values for the scan lines of other colors with respect to the standard scan line in the memory device. When forming images, the control device reads the data for the most distant standard scan line and the bending correction values for the scan lines of the other colors stored in the memory device, and carries out correction so that the laser irradiation position coincides with the standard scan line in accordance with the correction values via the sub scan deflecting element.

    摘要： An optical scanner includes a light source including a plurality of light emitting elements, a polygon mirror which deflects light from the light source for scanning a surface of a subject, an optical element arranged between the light source and the polygon mirror, having optical power in a sub scanning direction, a synchronous detector which detects the light deflected by the polygon mirror for synchronous detection and generates a signal for controlling a timing at which the scanning of the surface is started, and a fixing element which secures one end of the optical element. The light emitting elements of the light source are aligned with a certain tilt angle relative to the sub scanning direction. Light from one of the light emitting elements disposed closest to the fixing element in a main scanning direction is used for synchronous detection.
