An inkjet recording apparatus includes a nozzle, a charging electrode, a deflecting electrode, a storage device, and an authentication device. The nozzle atomizes a supplied ink into ink particles by exciting and ejecting the supplied ink. The charging electrode electrically charges the ink particles. The deflecting electrode forms an electric field that deflects the ink particles electrically charged. The storage device storing therein a program(s) that implements a predetermined printing function(s). The predetermined printing function(s) becomes executable upon connection of an authentication key to the authentication device.
