Abstract:
An inkjet printing apparatus includes a discharge head including orifices that discharge ink, a channel communicating with the orifices, a heating element that generates thermal energy for discharging the ink in the channel, a protection layer having a surface exposed to the channel and covering the heating element, and an electrode having a surface exposed to the channel; a tank that stores the ink to be supplied to the discharge head; an ink circulation unit that performs a circulation operation of circulating the ink between the discharge head and the tank; and a kogation removal unit that performs a removal operation of removing kogation generated around the heating element by applying a voltage between the protection layer and the electrode. The kogation removal unit performs the removal operation after the circulation operation is stopped.
