Abstract
An image forming apparatus includes a device-information storage unit configured to store a scanning frequency of an oscillating device; an image storage unit configured to store image data used for image formation; an image processing unit configured to perform an enlargement or reduction, in a direction orthogonal to a direction of the scanning of the laser beam and in accordance with a given parameter, on the image data stored in the image storage unit; a setting unit configured to calculate the parameter from the scanning frequency stored in the device-information storage unit and a predetermined reference frequency and configured to provide the parameter to the image processing unit; and a driving unit configured to drive a laser beam device according to the image data processed by the image processing unit.
