Abstract:
An ink-jet printer comprising:a rotary drum, having a dielectric peripheral surface, for rotating at a constant speed; a medium supply section for feeding a print medium to the rotary drum; a medium holding system for causing the print medium to be held on the peripheral surface of the rotary drum; and a print head section for printing an image by jetting ink onto the print medium held on the peripheral surface of the rotary drum while the rotary drum makes a predetermined number of rotations; wherein said medium holding system includes an elastic charging roller for charging the print medium fed by the medium supply section such that the print medium is attracted on the rotary drum with an electrostatic attraction force produced by the charging of the print medium, and roller pressing means for applying mechanical pressure to the charging roller to increase a nip width of the charging roller which presses the print medium against the peripheral surface of the rotary drum.
