An ink-jet print head with a chamber sidewall heating mechanism includes a substrate, an insulation layer on the substrate, a main channel penetrating through the substrate, a plurality of V-shaped micro-channels each having a diverging end linking with the main channel and a converging end linking with an ink chamber on the insulation layer, and a nozzle plate with a plurality of orifices formed on the ink chamber. The V-shaped micro-channels are perpendicular to the main channel and parallel to and arranged on the insulation layer. Each chamber sidewall includes a heater structure to evaporate ink in the chamber to form a bubble, which pushes the ink in the chamber to eject from the orifice.
