Substrate for liquid jet recording head for producing consistently shaped ink bubbles, liquid jet recording head provided with said substrate and method of recording with said recording head

摘要

A liquid jet recording head includes a substrate having a support and an electricity-heat converter arranged on the support. The heater converter includes a heat-generating resistor layer and a pair of electrodes electrically connected to the heat-generating resistor, with a heat-generating portion being formed between the pair of of electrodes. The heat generating portion includes a deforming portion that is at a temperature lower than the other portions of the heat generating portion during driving of the electrodes so as to produce a consistently shaped ink bubble and reduce random boiling. The invention also relates to a method of recording with the liquid jet recording head.
