ABSTRACT:
An ink jet recording apparatus which jets out a plurality of ink droplets at a predetermined cycle within a single drive period and such that the ink droplets are combined in the air to form a single ink droplet which is supplied to a recording sheet. A charge pulse generating circuit and a discharge pulse generating circuit which divide a drive period into a plurality of segments and output a pulse signal, having cycle Tp which is larger than the Helmholtz cycle Tc, in synchronism with an auxiliary print signal. A time constant adjusting circuit changes an output waveform of a constant current circuit with the pulse signal to increase the velocity of an ink droplet last jet out so that the velocity of the ink droplet allows the ink droplet to be combined, in the air, with an ink droplet previously jet out.
