Abstract
An image forming apparatus with a unidirectional magnification function, the apparatus comprising an original scanning unit for optically scanning an original in a predetermined direction so as to obtain an optical image, a variable magnification unit having first and second variable magnification mechanisms which vary magnifications of the optical image obtained by the original scanning unit in the original scanning direction, and in a direction perpendicular thereto, a photosensitive body which is movable in synchronism with the original scanning unit, an image forming unit for exposing the optical image onto the photosensitive body through the first or second variable magnification mechanisms of the variable magnification unit, so as to form an image which has the predetermined magnifications with respect to the original, and a unidirectional magnification unit for independently driving one of the first and second variable magnification mechanisms of the variable magnification unit.
