ABSTRACT:
There is described an ink-jet printer, which emits ink particles onto a recording medium to prints an image on the recording medium, and in which moving velocities of the ink particles are detected to perform stable emitting actions of the ink particles. The ink-jet printer includes: an ink-jetting head having a plurality of nozzles from which the ink particles are emitted; a velocity detecting section to detect moving velocities of the ink particles by measuring detection times at each of which each of the ink particles is detected; a calculating section to calculate an average value of the detection times measured by the velocity detecting section; and a head-drive controlling section that compares the average value calculated by the calculating section with a target value established in advance, to change a driving condition for the ink-jetting head so that the average value coincides with the target value.
