Abstract
A liquid jet recording apparatus has a full-line type recording head with discharge ports across a recording medium, a liquid path communicating with the discharge ports and having a thermal energy generating member for generating energy utilized to discharge recording liquid, a common liquid chamber for storing liquid to be supplied to the liquid path, the energy generating member, liquid path and common liquid chamber being disposed on one side of a substrate, and a storing tank for storing the recording liquid to be supplied to the recording head. Another liquid chamber is disposed on the other side of the substrate and is independent of the common liquid chamber. A temperature sensor detects the temperature of the recording head and recording liquid is circulated in the chamber when the temperature of the recording head exceeds a predetermined limit. A fan supplies cooling air in response to the circulation of recording liquid.
