1. An image recording apparatus for recording an image based on image recording data, said image recording apparatus including image recording heads relatively movable in a predetermined scanning direction along an image recording surface, said apparatus comprising: an image recording component group comprising a two-dimensional array of a plurality of image recording components, for forming a two-dimensional image recording dot group by a plurality of image recording element dots inclined at a predetermined tilt angle to said predetermined scanning direction on said image recording surface; and control means for modulating each of said image recording components at predetermined timing according to said image recording data; wherein an array pitch between adjacent ones of said image recording element dots, said tilt angle, an image recording pitch between image recording dots formed in said scanning direction, or a phase difference between image recording positions in said scanning direction of adjacent ones of said image recording element dots is set so that a jaggy pitch or a jaggy amplitude of jaggies produced because of the relationship between the array pattern of said image recording dots formed on said image recording surface and an image pattern based on said image recording data is of a predetermined value or less.
