Abstract
An ink-jet printer which can carry out high speed image formation and which can avoid image failure due to a defective nozzle includes a first printing head to emit ink particles, said first printing head being a line-type head in which a plurality of ink-jet nozzles are arranged in a line, and a second printing head to emit ink particles having a same color as that of the ink particles emitted by the first printing head. Alternatively, the ink-jet printer may include a printing head to emit ink particles, a nozzle checking device for detecting a defect of the ink-jet nozzle mounted in the printing head, and a driving unit for moving the printing head in a line direction.
