<P>PROBLEM TO BE SOLVED: To provide a liquid discharge head which has sufficient adhesiveness for a long time and ink discharge property, and an image forming device. <P>SOLUTION: The liquid discharge head includes: a nozzle plate having a discharge port for discharging liquid droplets; a flow path plate having individual liquid chamber in communication with the discharge port. The nozzle plate and the flow path plate are bonded by curing an epoxy bonding agent. The ink containing an amide series organic solvent and water is discharged. The amide series organic solvent amount is contained 20 wt.% or more in the ink, and contains N-methylpyrrolidone, 2-pyrolidone, 1,3-dimethyl-2-imidazolidinone, and one or more compounds indicated in a constitutional formula (1). The epoxy adhesive contains (A) an epoxy resin monomer without a hydroxyl, and (B) an amine series curing agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
