摘要： The invention concerns an image forming apparatus provided with an automatic writing-position determining device for forming an image always at a correct position on the recording material. The image forming apparatus includes an image forming section to form an image by writing each of scanning lines, an end position detecting section to detect an end position of a recording material in a direction orthogonal to a conveyance direction of the recording material, and a selecting section to select either an automatic writing-position determining mode or a predetermined writing-position determining mode. When the selecting section selects the automatic writing-position determining mode, the image forming section commences an image writing action from a writing start position determined on the basis of a detected result of the end position detecting device. When the selecting section selects the predetermined writing-position determining mode, the image forming section commences the image writing action from a predetermined writing start position set in advance.

摘要： In a method for compensating a variable image magnification in an optical zoom system, a magnified image is formed on a focal surface by projecting a document image through a projection lens and onto mirrors provided to an optical path length adjusting device. The position of the projection lens and the optical path length adjusting device are compensated so that an actual image magnification is the same as a selected nominal image magnification. An optional nominal magnification within a predetermined variable magnification range is selected. At least one of the projection lens and the variable optical path length adjusting device is moved so as to be in focus and then an actual image magnification at a position where the projection lens is in focus is measured. An actual focal length of the projection lens is calculated from the measured magnification according to equations with respect to magnification, focal length, principal points and so on. Each compensating position of the projection lens and the optical path length adjusting device in accordance with the selected magnification is determined, based on the calculated focal length and the optional nominal magnification.
