    摘要: An image formation apparatus which records an image on a recording medium is provided. The apparatus has a recording element array head on which plural recording chips are arranged, plural recording elements being arrayed on the recording chip, a reference clock generation unit for generating a reference clock, a main scan sync signal generation unit for generating a main scan sync signal by dividing the reference clock into 2n1 (n1: positive number) parts, an input unit for raster inputting image data for one line in synchronism with the main scan sync signal, a drive clock generation unit for generating a drive clock by dividing the reference clock into 2n2 (n2: positive number) parts and a drive unit for driving the recording chips in synchronism with the drive clock.
