Abstract: First humidified gas is supplied from a first supply port to a sheet to be conveyed, thereby increasing the moisture content of the sheet. Simultaneously, second humidified gas is supplied to a space where nozzles of the inkjet recording head are exposed, from a second supply port provided at a position closer to the inkjet recording head than the first supply port, thereby increasing the atmosphere humidity of the space. The part of the sheet of which the moisture content has been increased is made to enter the space where the atmosphere humidity has been increased, and recording is performed by the inkjet recording head.
