摘要： A head chip for an inkjet image forming apparatus. The head chip can include a heater formed on a substrate to generate heat, a chamber layer formed on the heater and provided with an ink chamber that receives inks, a nozzle layer formed on the chamber layer and provided with a nozzle in correspondence with the ink chamber, and a heat transfer layer transferring a part of the heat from the heater to the nozzle. According to the head chip, the inks sprayed through the nozzle are heated by the heat transferred through the heat transfer layer. Thus, the viscosity of the inks is reduced, so that the inks can be easily cut into ink droplets having a substantially spherical shape.
