There is disclosed an ink jet printhead which comprises a plurality of nozzles ( 3 ) and one or more heater elements ( 10 ) corresponding to each nozzle. Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble ( 12 ) therein. The generation of the bubble causes the ejection of a drop ( 16 ) of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Each heater element is formed of solid material, more than 90% of which, by atomic proportion, is constituted by at least one element, from the periodic table of elements, having an atomic number below 50.
