An oily inkjet ink comprises a pigment, a dispersant, and a water-insoluble organic solvent, wherein an ester solvent contained in the water-insoluble organic solvent is an ester solvent that is represented by the general formula: C
n
H
x
—COO—C
m
H
2m+1
, in which n represents an integral number falling within the range of 8 to 15, m represents an integral number falling within the range of 4 to 7, and x represents a number falling within the range of 2n−1 to 2n+1. The ester solvent is contained in a containing quantity falling within the range of 10% by mass to 30% by mass with respect to the total quantity of the ink.
