    摘要： An optical scanning device includes a polygon scanner that deflects and scans light beams, a body on which the polygon scanner directly mounted, and a heat dissipating unit that dissipates heat of the deflection scanning unit. The heat dissipating unit is located at a position on an outer surface of the body corresponding to the deflection scanning unit. The body is provided with a pair of wall portions on the outer surface. The wall portions face each other with the heat dissipating unit between them, and extend in a direction in which air blown by an air blowing unit flows to form an air-flow path.

    摘要： An exposure unit which exposes photoconductive drums having rotary axes thereof arranged parallel to each other on a single plane by light beams, includes one or more polygon mirrors each having a plurality of reflection surfaces, where the one or more polygon mirrors rotate about a common rotary axis. Each light beam is deflected by the one or more polygon mirrors and scans the surface of a corresponding photoconductive drum. The common rotary axis is separated from the rotary axes of the photoconductive drums by identical distances along respective normals which are perpendicular to both the common rotary axis and the rotary axes of the photoconductive drums.

    摘要： A method and apparatus of image forming includes an optical writing device and an image carrier. The optical writing device includes a housing, a dustproof member, a light source, and a shield. The housing is provided with an opening. The dustproof member is light permeable and closes the opening. The light source is installed in the housing and irradiates the image carrier with a light beam through the dustproof member. The shield is movable between a first position to cover the dustproof member and a second position to uncover the dustproof member. The optical writing device also includes a cleaner attached to the shield and contact the dustproof member. The optical writing device also includes a driver for moving the shield. The optical writing device further includes a positioning mechanism for positioning the shield to the first position by using the driver.

    摘要： An image forming apparatus includes at least one image carrier. An endless transfer belt directly or indirectly receives toner images and pattern toner images from the image carrier and is spanned around and surrounds a drive roller and driven rollers. A position shift detector detects positions of pattern toner images formed on the image carrier. Pattern toner images are formed on the image carrier at an interval of 1/N of a circumferential length of the image carrier, where N is an integer equal to or greater than 1. The pattern toner images are transferred from the image carrier onto the transfer belt over one cycle length of the transfer belt. The position shift detector detects positions of the pattern toner images to obtain position shift data. Moving average values of N number of the position shift data are calculated.
