Abstract
A liquid discharging head cartridge that prevents a discharging head from being damaged due to exposure to liquid held in a liquid container during storage including the distribution period of a liquid discharging head cartridge, and ensures the reliability of the liquid discharging operation by the discharging head. An ink jet head cartridge includes an ink blocking member that is provided in the middle of an ink flow path and blocks ink supply to a recording head. The ink held in an ink container does not enter a section of the ink flow path between the ink blocking member and the recording head due to blockage by the ink blocking member.
