Abstract

An image forming apparatus is provided with a zoom processing circuit, a scanning optical system and an enlarging/reducing circuit. The enlargement/reduction of the formed image in the main scanning direction is performed by the zoom processing circuit and an enlarging/reducing circuit, and the enlargement/reduction in the sub scanning direction is performed by the scanning speed of the scanning optical system and the enlarging/reducing circuit. When a magnification within a magnification range depending on the zoom processing circuit and the scanning optical system is specified, the enlargement/reduction of the input image data by the enlarging/reducing circuit is not performed.
