Abstract:
1. An image recording apparatus for recording an image on a recording medium by scanning a surface of the recording medium with a light beam, comprising a recording head including a plurality of light sources each for emitting a light beam toward the recording medium; a moving part for moving said recording head relative to the recording medium in a main scanning direction and in a sub-scanning direction orthogonal to said main scanning direction; and a controller for controlling said moving part; a setting part for selecting a first integer N from a group of submultiples of a second integer M, based on information about the sensitivity of the recording medium or a recording intensity, where the second integer M is the number of light sources arranged in said recording head in the sub-scanning direction, and said group of submultiples of the second integer M includes at least two submultiples of the second integer M; wherein said controller controls said moving part so that said recording head moves through a distance corresponding to one N-th of a recording width of said recording head in said sub-scanning direction each time said recording head makes a single scan in said main scanning direction, to thereby cause said recording head to make N repeated recordings at the same position on the recording medium.
