Inkjet ink and inkjet recording device

An inkjet recording device, comprising:

• an ejecting unit configured to eject an inkjet ink,
• wherein the inkjet ink comprises:
• a water-dispersible colorant;
• a surfactant;
• a penetrating agent;
• a water-dispersible resin;
• a wetting agent comprising at least polyhydric alcohol having an equilibrium moisture content of 30% by mass or higher at 23° C., 80% RH;
• a compound of formula (1);
• water;
• and
• at least one selected from the group consisting of a compound of formula (2), a compound of formula (3), and a compound of formula (4),
• wherein the water-dispersible colorant is at least one selected from the group consisting of a self-dispersible pigment, a pigment dispersed by a pigment dispersing agent, and resin particles each comprising a pigment,
• wherein a total amount of the water-dispersible colorant and the water-dispersible resin is from 8% by mass to 35% by mass, and
• wherein a mass ratio of the water-dispersible resin to the water-dispersible colorant is from 2 to 8:
• wherein R1 is a C4-C6 alkyl group,
• wherein R2 is a hydrogen atom, a methyl group, or an ethyl group, and R3 is a C1-C4 alkyl group,
• wherein R4 is either a methyl group or an ethyl group, and R5 is a hydroxyl group, a C1-C8 alkyl group, a cycloalkyl group, or an aryl group,
• wherein R6 and R7 are each independently a C1-C8 alkyl group.
