Abstract:
1. An image forming apparatus comprising: a scanning unit configured to scan an image in a main scanning direction by a laser beam; a clock output unit configured to output a clock showing a period of one pixel; an image output unit configured to output one pixel of image data; a forming unit configured to form pixel segments on a pixel unit basis by dividing by a preset number, the pixel constructing the image data; a control unit configured to perform insertion/extraction control of a pixel segment so that exposure lengths in the main scanning direction by the scanning unit are equalized on a pixel segment unit basis; a dividing unit configured to divide an area of an image in the main scanning direction into divided areas in accordance with a magnification such that exposure lengths are controlled so as to be equalized; a setting unit configured to set a reference area for performing the insertion/extraction control in each of the divided areas; and a deciding unit configured to decide a position where the insertion/extraction control in each of the divided areas is performed, in accordance with attribute information of the image data in the reference area.
