SOLUTION: A head section has the plurality of inkjet heads juxtaposed in a sub-scanning direction. The nozzle array is formed on a nozzle plate of the inkjet head such that the nozzles are arranged in a line in a direction diagonal to the conveyance direction of the recording paper by 20 degrees. A screen angle of each color is set to be different from the inclination angle of the respective nozzle array. COPYRIGHT: (C)2005,JPO&NCIPI
