Abstract
Disclosed is an image forming apparatus which provides an image of an excellent quality which has a less variation in resolution and suppressed linear irregularity. A rod lens array includes two rows of rod lenses stacked one on the other. An LED array is offset by a predetermined offset amount from a plane passing the median position between the first row of rod lenses and the second row of rod lenses. This structure can realize an LED printer head which reduces a variation in the resolution of the rod lens array, thereby suppressing linear irregularity, and can thus provide an image having an excellent quality.
