摘要：
An image processing apparatus comprising a halftone processing section which executes a halftone process for input image data, wherein the halftone processing section executes the halftone process, by using a dither matrix, the order of producing the dots in the halftone process is consecutive in a main scanning direction, in the pixel block, and the starting position of producing the dots in the pixel block is shifted in the main scanning direction by no less than two dots from the starting position of the adjoining pixel block in the sub scanning direction.
