A recording method for using a line-type recording apparatus to scan a recording medium with a plurality of line heads once for recording, the line heads having a width greater than or equal to the recording width of the recording medium, the method including a treatment liquid deposition step of depositing a treatment liquid containing a coagulant on the recording medium, and an ink deposition step of ejecting a coloring ink composition from the line heads to deposit the coloring ink composition on the recording medium, wherein in the ink deposition step an identical coloring ink composition is ejected from a first line head placed on the upstream side in the transport direction perpendicular to the width direction of the recording medium and from a second line head placed on the downstream side in the transport direction.

A pretreatment liquid for inkjet recording contains a photobase generator that produces an organic amine compound through light exposure. An inkjet recording apparatus forms an image on an image formation area of a recording medium. The inkjet recording apparatus includes a pretreatment section, a light exposure section, and a recording head. The pretreatment section ejects the pretreatment liquid for inkjet recording toward the image formation area of the recording medium. The light exposure section performs light exposure on the image formation area of the recording medium to which the pretreatment liquid for inkjet recording has been ejected. The recording head ejects an ink toward the image formation area of the recording medium subjected to the light exposure to form the image.
