There are provided an inkjet head, an inkjet image forming apparatus, a nozzle plate manufacturing method, and an inkjet head manufacturing method capable of improving durability against wiping on an ink discharge surface. The inkjet head includes a nozzle substrate including nozzle holes from which ink is discharged. The nozzle substrate has an irregularity structure formed on an ink discharge surface such that neither ink particles contained in the ink nor a wiping member that wipes the ink discharge surface get caught by the irregularity structure.
