Abstract
An inkjet printhead that has a pair of electrodes, a heater having contacts abutting the pair of electrodes, a heater element for generating a vapour bubble in a quantity of ink and sloped side portions extending between the heater element and the contacts and, a nozzle spaced from the heater such that ink is ejected through the nozzle in response to the generation of a vapour bubble. The heater element has higher electrical resistance than the contacts and the sloped side portions.
