Claim:
A method of recording on a sheet using an inkjet type recording head in which nozzles are formed, the method comprising: a first step of supplying a first humidified gas through a first supply port to a surface of the sheet on which an image is to be formed; a second step of supplying a second humidified gas through a second supply port to a space where the nozzles are exposed; and a third step of performing, using the recording head, recording on a portion of the surface of the sheet which has entered the space where atmospheric humidity has been increased by the second step, after a moisture content of the portion of the surface of the sheet has been increased by the first step, wherein a plurality of the recording heads are arranged along a direction in which the sheet is conveyed, wherein in the second step, at least a part of the second humidified gas supplied from the second supply port flows along the direction of sheet conveyance through a space that includes a gap between nozzles of the plurality of the recording heads and the sheet, and wherein a flow velocity of the second humidified gas is set to 1 m/sec or less at the gap.
