Abstract:
An image forming apparatus comprising a recording head including a plurality of recording elements for recording a plurality of pixels, the recording elements being disposed in an intermittent relative feed direction with different distances between adjacent recording elements including at least three different distances (aÃ—d), (bÃ—d) and (cÃ—d), where a, b, c are natural numbers which are different from each other, and d is a minimum interval between adjacent pixels in the intermittent relative feed direction, such that irregularities in density, generated in an image formed by the recording elements, due to a feed amount error between a recorded material and the recording head in the intermittent relative feed direction, are generated in only an area with a spatial frequency of 1 lp/mm or more.
