ABSTRACT:
An ink jet recording head is described in which nozzles can be arranged at a high density, which can be driven at a high frequency, and in which the nozzles do not interfere with each other.
An ink jet recording head is connected to a buffer tank via a communication path which is close to an ink flow path of the recording head and which elongates along the arrangement direction of the pressure generating chambers. Therefore, pressure variation due to a reverse flow from the pressure generating chambers is absorbed by the tank.
