Abstract
Provided is an image recording method including an applying step of applying a pretreatment liquid containing water and an aggregating agent onto an impermeable base material and applying an ink containing water and a colorant onto a region of the impermeable base material where the pretreatment liquid has been applied, and a drying step of drying the ink applied onto the region to obtain an image, in which the drying step includes blowing of hot air at a wind speed of greater than 15 m/s to the ink applied onto the region, and in a case where the number of grams of the ink applied per 1 m2 in an image area with a density of 100% is defined as X, and the number of grams of the pretreatment liquid applied per 1 m2 in the image area with a density of 100% is defined as Y, a viscosity of a kneaded material obtained by adding (6.5Y/X) mg of the pretreatment liquid to 10 g of the ink and defoaming and kneading the mixture at 200 rpm for 5 minutes is in a range of 30 mPa·s to 500 mPa·s.
