摘要： Provided is an image forming apparatus that performs smoothing in conversion of pseudo high resolution without using a large translation table. A smoothing process part performs smoothing based on a density of a peripheral pixel that adjoins a target pixel on edge. When a density change between both sides of the target pixel in a sub scanning direction is larger than a density change between both sides of the target pixel in a main scanning direction, a density of a plurality of pixels after conversion of pseudo high resolution of a sub scanning direction corresponding to the target pixel is mutually changed. Also, when a density change between both sides of target pixel in the sub scanning direction is not larger than a density change between both sides of the target pixel in the main scanning direction, the density set to the same.

The scanning optical system includes individual lenses which are individually arranged for the respective light beams and have a plane shape symmetric in the main-scanning direction and satisfies a predetermined condition, and an optical axis of the individual lens is arranged obliquely to the normal line of the scanning surface in the main-scanning cross section so as to satisfy a predetermined condition.
