Abstract:
1. An image forming apparatus comprising: an ink-ejecting unit that has a full line recording head aligned in a width direction which is substantially perpendicular to a transport direction of a recording sheet and that ejects ink onto the recording sheet through a plurality of orifices of the recording head in accordance with print data to be printed in response to a print instruction, thereby printing an image; a region dividing unit that divides, in the width direction of the recording sheet, a print region of the recording sheet into a user region and a print control region, the print data being printed in the user region, print control information being printed in the print control region, the print control information being referred to in post-processing of the recording sheet; and a preparatory ejection unit that preparatorily ejects, before printing of the image, ink onto the recording sheet through the plurality of orifices so that an amount of ink ejected through an orifice for the print control region among the plurality of orifices is smaller than an amount of ink ejected through an orifice for the user region among the plurality of orifices.
